System Board P515-0001724C?

SCSI Termpacks are Dale 8 pin SIPPs, 221-331G (dtd '93)
DRAMs are (x8) Siemens HYB514256BJ-70

Processor Card GAL-LITE CPU W/Cache Adapter, FCC C6P3350-66

SX board has a surface mounted SX, no switch, and no L2 cache. The DX2 board has ZIF socket with a switch block next to it, and an L2 cache. Cache Memory Socket supports 64 KB or 128 KB cache module You need the latest BIOS of 1.09.00 or later. 83 MHz upgrade really does improve things...

CPU Settings on SW1

Note: Processor card will not operate if more than one processor type is selected.

Memory

Industry standard parity 70 ns 72-pin SIMMs. Six sockets available for memory up to 192 MB.

Features

20 MB/second Micro Channel bus.

Two 50 to 19,200 baud serial ports, One 8-bit parallel bi-directional port.

The 3350 has 4 drive bays. Two are external (the top external bay can hold a 5 1/4" device like a CDROM drive). The other bays are for 3 1/2" devices only. In order to get the fourth bay (the "upper" "rear" bay, two sheet metal extenders are installed above bay three (bay three is the "lower" "rear" bay). If bay four is used, you cannot use the upper front bay for a 5 1/4" device (there is not enough room). 4 MCA slots. One is an MCA video slot, and has the extra connector for the Clarity 1 card.

Video System

NCR 77C22E. with 1 MB of video ram. Capable of 1024x768 256 colors.

Clarity 1 Video Board (Bam-Bam?)

There was an optional video board built specifically for the 3350 called the "Clarity 1". It plugged into a proprietary slot, and was capable of up to 1280x1024. The Clarity 1 has 2 MB. The feature/kit number for the clarity 1 is 3350-F/K256.

> I have a NCR 3350 with a Clarity I video card. Does anyone know if there are Win95 drivers available for this card? Or even who manufactured the Clarity I card for NCR?

Joey Blankenship says:
   MCNCR designed and manufactured the Clarity I card in-house. I was project leader and developer for the Windows 3.1 & NT device drivers for this card. I also worked on testing the existing 3.1 drivers under Win95. They appeared to work fine. I believe that the official position of NCR is that this card is not supported under Win95, but I'm not sure. However, we did get the drivers working both by upgrading and existing Win3.1 installation and installing under Win95. No mods were made to the drivers.

Install CD-ROM

You need DOS CD-ROM drivers to install Win 95 or NT. Take a look HERE.

You have a 53c94 SCSI host adapter on the motherboard. You will need two drivers - the CAM driver and the CD-ROM driver. These two statements must be added to the CONFIG.SYS file in the following order - after any memory manager drivers (such as HIMEM.SYS or EMM386.SYS) and must precede any other "DEVICE=" statements.

CONFIG.SYS:

DEVICEHIGH = c:\util\ncr\camc9x.sys
DEVICEHIGH = c:\util\ncr\diskidd.sys
DEVICEHIGH = c:\util\ncr\cd-tosh.sys /d:msc001

DEVICE = a:cdscsi-2.sys /D:ASPICD0

Some of the older 1x CD-ROM drives (like the Sony or the Toshiba) needed a specific driver (in place of cd-scsi-2.sys).

Another good utility to download from NCR is PUTSIG which will fix a Reference Disk that's been corrupted by Win95.
