DESCRIPTION The RT Personal Computer System is an advanced computer designed for the technical professional, for increased personal productivity, as well as for technical applications in engineering, science, and CAD/CAM. It includes technology not previously available in IBM Personal Computers: an IBM-developed, high-performance, 32-bit microprocessor and 40-bit virtual memory management unit, floating-point, high capacity fixed-disk drives, large system memory, and an optional IBM Personal Computer AT Coprocessor. The optional features and attachable devices supported include both newly developed products as well as many existing IBM Personal Computer products. The multi-tasking, multi-user system is managed by the IBM RT Personal Computer Advanced Interactive Executive (AIX(TM)) Operating System, derived from UNIX(1) System V(2) but with significant IBM-developed enhancements: virtual machine support and hardware assisted virtual system management, file system improvements, floating-point support, data management, support for high-resolution, all-points addressable (APA) displays, installation/configuration support, and an interface designed for ease-of-use. The RT Personal Computer model 020, 025, or A25 can be attached to an IBM 5080 Graphics System to provide a compact, modular graphics system that can support computer-aided design capabilities on the IBM 5080 Graphics System while retaining an independent but integrated relationship with larger hosts. (Model A25 is a model 025 with an IBM RT Personal Computer 5080 Attachment Adapter (#7860) and without a keyboard. A keyboard is not required when attached to a 5080.) Additional details of this configuration are given in IBM Product Announcement 186-009, dated January 21, 1986. (1UNIX is a Trademark of AT&T Bell Laboratories (2The AIX Operating System is based on INTERACTIVE Systems Corporation's IN/ix*, which is based, in turn, on UNIX System V, as licensed by AT&T Bell Laboratories. Portions of the modifications and enhancements were developed by IBM and portions were developed by INTERACTIVE under contract to IBM. * Registered trademark of INTERACTIVE Systems Corporation. TECHNOLOGY The system processor has a 32-bit, reduced instruction set computer architecture, developed by IBM on a single chip using 2-micron FET technology. It has sixteen 32-bit general purpose registers and uses 32-bit addresses and data paths. The microprocessor is controlled by 118 simple 2-and 4-byte instructions. An IBM-developed advanced memory management chip provides virtual memory address translation functions and memory control. It provides a 40-bit (1 terabyte) virtual address. The reduced instruction set computer architecture provides a system which is oriented toward pervasive use of high-level language programming, while providing a storage and I/O organization to enable the central processing unit to execute most register-to-register instructions in a single cycle. PERFORMANCE The IBM RT Personal Computer microprocessor has a cycle time of 170 nanoseconds and typically executes at 1.6 to 2.1 million instructions per second (MIPS), depending upon the actual instruction mix. It should be noted, however, that actual system throughput is dependent on numerous other factors. For central processing unit intensive tasks, the RT Personal Computer has approximately two times the execution speed of an IBM Personal Computer AT model 099. The RT Personal Computer has a 4-byte wide memory interface with 8-bits of error correcting code (ECC), which provides a bandwidth of 23.5 Mb/second. The I/O bus bandwidth is 2 to 4 Mb/second. The optional Floating-Point Accelerator increases the IBM RT Personal Computer's capability to process floating-point operations and has an approximate performance up to 200 thousand Whetstone instructions per second (KWIPS) when supported by the AIX Operating System (5669-061) (#5034). The Floating-Point Accelerator normally operates in virtual mode and provides support for the format and basic operations defined by the ANSI/IEEE 754-1985 Binary Floating-Point Standard. The additional operations in the standard are supported when the AIX Operating System is used in conjunction with the Floating-Point Accelerator. When used in conjunction with Personal Computer AT Coprocessor Services (5669-059) (#5030) and a dedicated Personal Computer display (IBM 5151 or IBM 5154) which is recommended for improved performance, the IBM Personal Computer AT Coprocessor option provides the capability to run many IBM Personal Computer AT programs concurrently with and under the control of the IBM RT Personal Computer main processor using only the system memory. Performance will be less than that of the Personal Computer AT. In general, the Coprocessor will operate with performance better than the IBM Personal Computer XT when memory is shared with the RT Personal Computer main processor. The performance can be improved substantially (up to twice the PC XT performance in processor-intensive or disk-intensive tasks) if the dedicated IBM Personal Computer AT 512Kb Memory Expansion Option (#0203) is installed. CONFIGURATION The 6150 models 020 and 025 workstations and the 6151 model 010 workstation with their associated options and attachments form the hardware base. They offer the capability to configure stand-alone and clustered workstations. The 6150 model A25 serves as a private host executing the graphics application for a 5080 Graphics System workstation via a serial link adapter which is standard with this model. An appropriately configured model 020 or 025 can also be equipped for use in this configuration by addition of a 5080 Attachment Adapter (#7860). (Consult specific application requirements for recommended configuration of fixed-disk and memory.) All models of the RT Personal Computer are based upon the high-performance, IBM-developed, 32-bit microprocessor and 40-bit virtual memory management card. The processor operates at a 170-nanosecond cycle time. Two-way memory interleaving results in overlapped memory accesses, providing the equivalent of a 170-nanosecond memory cycle. All models provide full 32-bit processing and 40-bit virtual addressing capability. The I/O bus provides a path for 16 data bits with 24-bit addressing. All models of the RT Personal Computer are equipped with a high capacity (1.2Mb) diskette drive and an integrated date/time clock with battery backup. Models 010, 020, and 025 are also provided with a keyboard with a layout that is similar to the IBM 3161 ASCII Display Station, and attached cable. Standard memory on the models 010 and 020 is 1Mb and on the model 025, standard memory is 2Mb. In addition, models 010 and 020 are equipped with a 5-1/4-inch fixed-disk drive with a capacity of 40Mb of storage, while model 025 has a 5-1/4-inch fixed-disk drive with a capacity of 70Mb of storage. Models 020 and 025 each have two standard asynchronous (RS-232C) serial ports with direct memory access in the base unit. These serial ports are recommended for attachment of high data rate devices such as the IBM 3812 Pageprinter. Each model can be further expanded through customer setup options. Memory can be expanded to 4Mb via an optional 1Mb or 2Mb Memory card in the dedicated card slot. Additional direct-access storage is available for models 020 and 025 only by adding up to two more fixed-disk drives, and a second high capacity diskette drive (1.2Mb) or IBM Personal Computer AT dual-sided diskette drive (320/360Kb). These combinations result in a maximum fixed disk storage of 210Mb and with a maximum diskette storage of 2.4Mb. Fixed-disk backup for save/restore of recorded information is available through the optional IBM 6157 Streaming Tape Drive. (See IBM Product Announcement 186-008, dated January 21, 1986. The 6157 tape cassettes also provide a medium for data interchange between systems. Models 020 and 025 are closely related to one another in that the same hardware options are available on each and the same software product offerings execute on each. All models are related to the existing Personal Computer product family through support of an optional IBM Personal Computer AT Coprocessor card and the associated software support, and utilization of the IBM Personal Computer AT bus. Model 010 has six feature slots and the models 020 and 025 contain eight feature slots which support devices, features, or IBM Personal Computer AT memory. Six of the slots (five in model 010) may be occupied by either RT Personal Computer or Personal Computer AT 16-bit option cards or by Personal Computer 8-bit option cards. Two slots (one in model 010) support 8-bit options only. As shipped by IBM, all models use one of the 16-bit slots for the standard combination fixed-disk and diskette drive adapter. In addition, there are two additional dedicated slots for system memory cards, one of which has the factory installed memory (1Mb for models 010 and 020 and 2Mb for model 025). There is also an additional dedicated slot for the optional Floating-Point Accelerator. All models also include a security keylock as standard, which, when locked by the user, can help to prevent removal of the RT Personal Computer cover, initialization of the system, and entry of commands or data from the keyboard. A programmable speaker, which can be used to produce tones, is also provided in the keyboard. The keyboard is standard on the models 010, 020, and 025, and is attached to the RT Personal Computer via an attached 2.5-meter (8.2-foot) cable, permitting a variety of workspace configurations. The keyboard uses a keyboard layout similar to that recently announced with the IBM 3161 ASCII Display Station. The keyboard, with 101 keys, a 30 mm height, and adjustable tilt, offers commonly used data and word processing functions along with separate typewriter and numeric keypads. Cursor keys, arranged in an inverted "T" pattern, are independent of numeric keys. Key-location enhancements and light-emitting diode (LED) mode indicators (cap lock, insert mode, scroll lock) improve keyboard usability. Special symbols may be accessed with a combination of keys. In the case of the model A25, which is for use with the 5080 Graphics System, the keyboard is provided with the 5080 rather than as a part of the 6150 Model A25. OPTIONAL FEATURES IBM RT PERSONAL COMPUTER FLOATING-POINT ACCELERATOR (#4758) The Floating-Point Accelerator plugs in to a special slot (not an I/O feature slot) on the RT Personal Computer system board. It supports both single (32-bit) and double (64-bit) precision floating-point operations using 32 sets of 14 registers (32-bits each) provided in the Floating-Point Accelerator. This option provides significant performance improvement for floating-point calculations. It supports the format and basic operations defined by the ANSI/IEEE 754-1985 Binary Floating-Point Standard. The IBM RT Personal Computer Advanced Interactive Executive Operating System (5669-061) (#5034) is required in order to support additional IEEE 754 operations and exception handling. IBM RT PERSONAL COMPUTER 1MB MEMORY EXPANSION (#8222) One additional 1Mb memory expansion may be added to any model. This option increases the model 010 or 020 memory from 1Mb to 2Mb and the model 025 memory from 2Mb to 3Mb. Memory is divided into two "arrays" of 512Kb with interleaving to overlap memory access and achieve the equivalent of 170-nanosecond cycle time. Four data bytes and one error correcting code (EEC) byte are transferred at a time over a 32-bit data path plus 8-bit ECC. IBM RT PERSONAL COMPUTER 2MB MEMORY EXPANSION (#4739) One additional 2Mb memory expansion may be added to any model. This option increases the model 010 or model 020 memory from 1Mb to 3Mb, and the model 025 memory from 2Mb to 4Mb, and may also be used to upgrade the model 010 or model 020 memory to 4Mb (with complete replacement of the 1Mb memory that comes with the machine). Memory is divided into two "arrays" of 1Mb with interleaving to overlap memory access and achieve the equivalent of a 170-nanosecond cycle time. Four data bytes and one ECC byte are transferred at a time over a 32-bit data path plus 8-bit ECC. ADDITIONAL FIXED-DISK STORAGE Fixed-disk storage on the model 020 or 025 may be expanded by up to two additional fixed-disk drives (not available on the model 010). Space and power are provided in the system unit for up to three fixed-disk drives. The first two fixed-disk and diskette drives use the standard combination fixed-disk and diskette drive adapter in the system unit. When a third fixed-disk drive is to be added to an RT Personal Computer system unit, a Personal Computer AT fixed-disk and diskette drive adapter and cable must be installed in a 16-bit feature slot as a prerequisite. Either the 40Mb or 70Mb fixed disk-drives described below can be added as the second and third drive for models 020 or 025. Both drives have the same physical size and both have a dedicated landing zone for the read/write heads to protect the drive and its contents during shipping, movement, or storage. IBM RT PERSONAL COMPUTER 40MB FIXED-DISK DRIVE (#4735): This disk drive is standard as the first drive in the RT Personal Computer models 010 and 020.

Each drive is fully self-contained and consists of a spindle drive system, a read positioning system, and a read/write/erase system. (A second diskette drive is not available on the model 010). IBM PERSONAL COMPUTER AT HIGH CAPACITY DISKETTE DRIVE (#0206): This is a half-high, 5-1/4-inch, dual-sided, high-capacity drive with 1.2Mb storage capacity. One drive is standard in every IBM RT Personal Computer. An optional second drive may be installed in the system unit of the models 020 or 025. Both drives use the standard fixed-disk and diskette drive adapter in the system unit. The drive uses the new 96-TPI, high density media. In addition, it will read 48-TPI, single- or dual-sided media written for the IBM PCjr, IBM Personal Computer, IBM Personal Computer XT, IBM Portable PC, and IBM Personal Computer AT, giving a high level of compatibility with existing applications. This drive can also write on the 48-TPI media. Once the 48-TPI media has been written in this drive, it may only be read on a high-capacity diskette drive. Characteristics o 1.2Mb storage o 512 bytes per sector o 15 sectors per track o 96 tracks per inch o Two sides o 80 tracks per surface o 360 RPM o Supports 300 and 500K bits/second data transfer rate o 98 ms average access time in 96-TPI mode IBM PERSONAL COMPUTER AT DUAL-SIDED DISKETTE DRIVE (#0207): This diskette drive permits read/write interchange capability with the 320/360Kb diskette media available on the IBM Personal Computer, Personal Computer XT, IBM Personal Computer AT, IBM Portable PC, and IBM PCjr. It is a half-high, 5-1/4-inch, dual-sided drive with a 320/360Kb storage capacity which also supports 160Kb single-sided diskettes. This drive is available for models 020 and 025, and uses the standard fixed-disk and diskette drive adapter in the system unit. Characteristics o 320/360Kb of storage o 512 bytes per sector o 8/9 sectors per track o Two sides o 105 ms average access time o 40 tracks per surface o 48 tracks per inch o 300 RPM o Transfer rate of 250K bits/second IBM PERSONAL COMPUTER AT FIXED-DISK AND DISKETTE DRIVE ADAPTER (#3428): One of these adapters is included in all models of the RT Personal Computer for attaching the first two fixed-disk drives and two diskette drives on the models 020 and 025 (standard fixed disk drive and diskette drive on model 010). A second adapter is available for attaching the third fixed-disk to the model 020 or model 025. The adapter supports the attachment of both the 40Mb and 70Mb fixed-disk drives and the high capacity diskette drive as well as the dual-sided diskette drive. Fixed-disk data rate is 5M bits per second. Diskette data rates are 250/300/500K bits per second. The adapter requires a 16-bit feature slot and a Fixed-Disk Attach Cable (#8541) when used as a second adapter. IBM RT PERSONAL COMPUTER MOUSE (#8426): This mouse provides a two-button mechanical device to provide positional input for screen pointing and cursor movement on a display screen. It includes a 2.5-meter (8.2-foot) cable and plugs into a specially keyed locator port on the IBM RT Personal Computer system unit. The adapter is included in the standard system electronics so no additional adapter is required. A snap-lock cover opens easily for routine cleaning of the rollerball. If the RT Personal Computer Mouse is attached to the system, the IBM 5083 Tablet cannot also be concurrently attached, since both attach through the locator port. LIGHTED PROGRAM FUNCTION KEYBOARD (#4710): The lighted program function keyboard is a separate assembly with 32 keytops in which a bright indicator light is imbedded in each key top for easy viewing from the side. They are turned on and off under application control to indicate which keys may be selected at a given moment. Correspondingly, a unique signal is returned to the application for any key pressed. In this way, a user may interact with an application. The device is supplied with a cable that plugs into the RT Personal Computer 5080 Peripheral Adapter via a cable supplied with the RT Personal Computer 5080 Peripheral Cable Kit (#7564), giving a total cable length of 2.4 meters (7.9 feet). DIALS (#8710): The dials unit is a flat, compact, low-profiled, desk-top device with eight cone-like dials. The dials may be turned continuously in either direction. Upon rotating the dials, a range of scalar values indicating direction and extent of rotation are signaled to the processor. An application can read and interpret this input for any suitable purpose, such as panning, zooming, and rotating two- or three-dimensional images. The device is supplied with a cable that plugs into the RT Personal Computer 5080 Peripheral Adapter via a cable supplied with the RT Personal Computer 5080 Peripheral Cable Kit (#7564), giving a total cable length of 2.6 meters (8.5 feet). IBM RT PERSONAL COMPUTER AT COPROCESSOR CARD (#4756): This feature provides for execution of many IBM Personal Computer and IBM Personal Computer AT programs concurrent with and under control of the RT Personal Computer 32-bit native processor. With appropriate program support (the IBM RT Personal Computer AT Coprocessor Services licensed program (5669-059)), this feature enables IBM RT Personal Computer workstations to emulate the IBM Personal Computer AT models 068 and 099. Performance will be better than that of the IBM PC XT (in general) but less than that of the IBM Personal Computer AT. Performance can be improved substantially if the IBM Personal Computer AT 512Kb Memory Expansion (#0203) is installed. A dedicated Personal Computer Display (IBM 5151 or IBM 5154) is also recommended for improved performance. This Coprocessor option must be installed in a designated 16-bit feature slot. Only one can be installed on an IBM RT Personal Computer system. An IBM Personal Computer AT Math Coprocessor (#0211) and IBM Personal Computer AT 512Kb Memory Expansion Option (#0203) may be used in combination with the IBM Personal Computer AT Coprocessor Card. The 512Kb Memory Expansion (#0203) is required for improved performance if the system memory is less than 2Mb. IBM PERSONAL COMPUTER AT MATH COPROCESSOR (#0211): The IBM Personal Computer AT Math Coprocessor is a numeric processor extension with floating-point, extended integer, and binary-coded decimal notation (BCD) data types. When installed in combination with the IBM RT Personal Computer AT Coprocessor Card (#4756), the Math Coprocessor operation conforms to the Proposed IEEE Binary Floating-Point Standard (Version 8.0). The Math Coprocessor is installed in a socket on the IBM RT Personal Computer/Personal Computer AT Coprocessor Card (#4756). The Personal Computer AT Coprocessor Card (#4756) is a prerequisite for the IBM Personal Computer AT Math Coprocessor. Only one Math Coprocessor can be installed on an IBM RT Personal Computer system. IBM PERSONAL COMPUTER AT 512KB MEMORY EXPANSION (#0203): This allows for the addition of 512Kb memory on the I/O bus. When this memory is used in combination with the IBM RT Personal Computer/Personal Computer AT Coprocessor (#4756), the Coprocessor programs execute substantially faster. This feature is plugged into a 16-bit feature slot on an IBM RT Personal Computer, and is required for optimal Coprocessor performance if the system memory is less than 2Mb. The performance characteristics of this memory expansion are the same as for other IBM Personal Computer AT user memory. Parity per byte and a 16-bit data path are supported. This memory can be accessed by the Coprocessor and/or the IBM RT Personal Computer system processor, but is intended for performance enhancement of the Coprocessor. A maximum of two 512Kb memory expansion features may be installed. Coprocessor memory addressing may be limited by the various operating systems and/or application programs used with the Coprocessor. IBM PERSONAL COMPUTER AT SERIAL/PARALLEL ADAPTER (#0215): This adapter provides a serial port and a parallel port. This card occupies one feature slot of either type (8-bit or 16-bit). The serial portion is fully programmable and supports asynchronous communications from 50 to 9,600 bits per second. It offers the same subset of the EIA RS-232C interface which is provided by the IBM PC Asynchronous Communications Adapter card but on a nine-pin external connector. The parallel portion of the adapter provides the ability to attach various devices such as printers that accept eight bits of parallel data, and provides the equivalent interface to the IBM Personal Computer Printer Adapter card. One or two IBM Personal Computer AT Serial/Parallel Adapters may be installed in any model. (However, only one parallel port may be used if the IBM Monochrome Display and Printer Adapter, (#4900) is also installed.) IBM RT PERSONAL COMPUTER STREAMING TAPE DRIVE ADAPTER (#4797): This option provides a quarter-inch cartridge (QIC-02) tape interface to the IBM RT Personal Computer. It supports attachment of the IBM 6157 Streaming Tape Drive (6298184), which provides for data interchange capability between all models of the IBM RT Personal Computer as well as for fixed-disk backup and restore at rates up to 5Mb/minute in image dump mode. The card requires a 16-bit slot on the IBM RT Personal Computer. System Unit, and provides a 37-pin "D" shell male external connector. Only one adapter can be installed on an IBM RT Personal Computer System. IBM PERSONAL COMPUTER 3278/79 EMULATION ADAPTER (#2507): This adapter provides a coaxial connection between an RT Personal Computer and 3274 Display Control Unit (in CUT mode only), or between a Personal Computer and the integrated display/printer adapter of either the 4331 Processor or the 4361 Processor. This adapter provides the "handshaking" between the two units. The RT Personal Computer 3278/79 Emulation licensed program running under the RT Personal Computer Advanced Interactive Executive (AIX) Operating System (55X8994) is also required for support of the connection. The DCA protocol is supported. A maximum of one adapter per RT Personal Computer system is supported. Customer-supplied cabling is required. Host programming is required for host interactive applications. IBM RT PERSONAL COMPUTER FOUR-PORT ASYNCHRONOUS RS-232C ADAPTER (#4763): This provides a subset of the EIA RS-232C interface signals on each of four 10-pin connectors for the independent attachment of ASCII terminals, asynchronous modems, or serial devices like plotters and printers (supports attachment of 3812 Pageprinter and/or the 4201 Proprinter with serial attachment #3000). Maximum data rate supported is 19.2Kbps over a 50-foot distance. This adapter may coexist in an RT Personal Computer with the RT PC Four-Port Asynchronous RS-422A Adapter (#4764) and the IBM RT PC 5080 Peripheral Adapter (#7561). A maximum of four of these adapters may be installed in the models 020 and 025 (maximum of three in model 010). Each adapter requires an available 16-bit feature slot. IBM RT PERSONAL COMPUTER FOUR-PORT ASYNCHRONOUS RS-422A ADAPTER (#4764): This provides a serial interface of EIA RS-422A signals on each of four 6-pin connectors for the independent attachment of ASCII terminals. Maximum data rate supported is 19.2Kbps over a distance up to 4,000 feet. (User-supplied surge suppressor required if distance is greater than 400 feet). The interface cable should not be installed outdoors. This adapter may coexist in an RT Personal Computer with the Four-Port Asynchronous RS-232C Adapter (#4763) and the RT Personal Computer 5080 Peripheral Adapter (#7561). A maximum of four of these adapters may be installed in models 020 and 025 (maximum of three in model 010). Each adapter requires an available 16-bit slot. IBM PERSONAL COMPUTER NETWORK ADAPTER (#0213): The PC Network Adapter is an option for connecting the RT Personal Computer to an IBM PC Network with IBM Personal Computers, IBM Personal Computer XTs, IBM Portable Personal Computers, or IBM Personal Computer ATs. Each RT Personal Computer requires one IBM PC Network Adapter card, which is supplied with a three-meter attachment cable. This cable can be connected directly to the PC Network and its associated translators, expanders, and cable kits. Customer-supplied software is required for proper utilization. Data may be sent to the PC Network Adapter from the RT Personal Computer via programmed I/O operations and received from it both via programmed I/O operations and direct memory access. IBM RT PERSONAL COMPUTER 5080 PERIPHERAL ADAPTER (#7561): This provides for the attachment of the Lighted Program Function Keys (#4710) and the Dials (#8710). This adapter is not required if the RT Personal Computer is to be connected to a 5080 Graphics System. In that case, the lighted program function keyboard and dials are connected to the IBM 5085 Graphics Processing Unit. This optional three-port card plugs into a 16-bit feature slot on the RT Personal Computer. The ports provide an RS-232C subset (XON/XOFF protocol only) as well as DC power to the attached devices. Modem control lines have been preconditioned on the adapter so that a plotter may be attached to any port using the XON/XOFF pacing protocol and the same printer/plotter cable used for attachment to the Four-Port Asynchronous RS-232C Adapter. Only one 5080 peripheral adapter is supported per IBM RT PC System Unit, and the total of this adapter and any four-port adapters installed on the RT Personal Computer may not exceed four per system (three per model 010). One RT Personal Computer 5080 Peripherals Adapter Cable Kit (#7564) is required for each 5080 peripheral to be attached. IBM RT PERSONAL COMPUTER 5080 ATTACHMENT ADAPTER (#7860): This consists of an adapter card and a cable kit. The adapter card plugs into a 16-bit feature slot in an appropriately configured RT Personal Computer model 020 or 025 and enables these models to connect to the 5080 Graphics System like the model A25. (This feature card is standard with model A25. Consult specific application requirements for recommended configuration of fixed-disk and memory.) Connection of the 5080 Graphics System workstation to the 6150 allows the 5080 to operate in a stand-alone environment with the 6150 as a private host. It allows the 5080 to be switched between stand-alone and System/370 mainframe interactive modes via the keyboard. (Note: Mainframe interactive mode requires a 5088 Channel Control Unit as a part of the 5080 configuration. The CAD/CAM Application must reset the IBM 5080 state, when switching between the mainframe and the IBM 6150.) Mainframe interaction provides the 5080 with access to System/370 applications. The attachment of the RT Personal Computer to the 5080 is made via a 4.6-meter (15-foot) industry standard coaxial cable supplied with the adapter and requires a 16-bit I/O slot. Customer supplied coaxial cable may also be used. See IBM RT Personal Computer Site Planning and Preparation Guide (GA23-1058). Transfer speed of information between the 6150 and the 5080 can be up to 2Mbits/sec. The 5080 Attachment Adapter includes the attachment card, a 15-foot coaxial cable for connection of the 5080 and RT Personal Computer, a 15-foot "Y" cable for switching the keyboard and tablet between the 5080 or RT Personal Computer, required microcode, and supporting publications.
