General Information

Model 5530 initially started as Low-Priced PC which was targeted to personal market. IBM Japan named the PC as "PS/55Z" to distinguish from PS/55 which was the main stream of MCA line targeted to business market. Before IBM joined into personal users market, IBM made a marketing model named 5530Z and sold it to a company called "Shinngaku-sha" (seemed to be a company worked for educational field) in Nov 1998.

5530-Z PS/55Z Model 5530Z286


CPU: 80286-10MHz
RAM: 1MB (max. 4MB)
Video: PS/55 Display Adapter
OS: JDOS 4.0

After one year of research and surveillance with 5530Z-286, IBM Japan rearranged 5530Z-286 in many ways and introduced PS/55Z 5530-Sxx which is usually described as 5530-ZSX (and probably PS/55 5530-T was introduced together with 5530-ZSX according to the date printed on a sales brochure of 5530-T03/T06). Main target of PS/55Z 30ZSX was personal market which was almost occupied by NEC with their PC9801 series.

5530-S PS/55Z Model 5530ZSX (?), Released in Nov 1989

Photo image is took from a brochure dated 11-90.
So it should be Stage II. Video cable is longer than Stage I system.

PS/55Z 5530ZS is the first model of MCA 5530 series (Except 5530Z-286 which had been sold to closed market for marketing purpose). In order to reduce retail price of expensive MCA line-ups, IBM Japan picked up i386SX CPU for PS/55Z. The basic design might be derived from PS/2 Model 25Z as you can see above photo. 12" color display was built in a body. Unlike PS/2 25Z, logic unit is slide-in type (no need to set the system up-side down while accessing system board and inner parts). AND, PS/55Z 5530 is an MCA system.

5530Z-SX is deviled to two groups, S0x and S1x (Ed: The former is refereed as Stage I and the latter as Stage II). All models use 386SX-16MHz.

The 5530, 5530-T04/T08 (Stage II) and 5530-S12/S14 (ZSX on Stage II) were listed in the Nov 1990 edition of the PS/55 System Guide.

Accessing System Board (From users manual 2nd edition dated Nov 1989)

Slide the blue lock lever to the left and lock the system unit not to swing.

Detach video connector from PS/55 Display adapter placed at the most upper slot (Display adapter IV should be placed there).

Unscrew two knobs at the middle of rear panel.

Place the connector to the "foxhole" prepared at the support guide for the connector cover.

Note: The video cable is very short and will not reach to the middle slot.

Grab the bottom edge of the base unit and pull it backward slowly till it will stop sliding.

Hold the base unit and pull it upward slightly and then slide it backward so that you can pull the base unit completely.

PS/55 Model 5530-T

Model 5530-T Brochure

The body, outer case and screen are all same with model 5530ZSX.
i386DX-20MHz CPU was given and the model was classified to PS/55.
(Want to see sales brochure? Click HERE)

A sales brochure of 1st model of 5530-T (T03 & T06) was dated as 11-89 which means Nov. 1989.
If so, 5530-T03/06 was Introduced to the market together with 5530Z-SX in Nov. 1989.
Next models, T02/T04/T08, were introduced in OCt. 1990.

486BL2-66 upgrade sub-board from Kingston was available. To use this parts, an interposer which changes the position of pin #1 is required. Not sure for 486BL3 upgrade by Evergreen if it could be fit in the planar.

Built-in Display
12" color display (long persistence phosphors) was integrated into the body.
Character mode ; 1066 x725 dots
Graphics mode; 1024 x768 dots

72pin SIMM socket x 3. 2MB/80 ns parts is standard.
One double-decked 4MB SIMM P/N 23F2165 can be used.
Total 8MB in combination of 2MB+2MB+4MB is the MAX on the planar according to users guide.

Actually 5530-T can take 24MB of RAM in combination of 3x 8MB 80 ns SIMMs on the planar. Not sure if PC DOS 7 can actually see total 24MB of RAM. I've tested JDOS5.0 + HIMEM.SYS in PC DOS 7.0 on the box but I got only 16MB of RAM reported using MEM command (this combination works for other 486 class PS/55s).

ESDI (DBA2) 30MB to 80MB depending on model-type.
T02 was 2 FDD model and without HDD.

2 Mode drive for all models.

BUS Riser
5530-T has only 3 MCA slots on it's riser card. 1 slot should be occupied with a PS/55 Display Adapter, hence only 2 slots are left for users.

Version 1.50 based on DOS/V is the latest.
In order to use XGA, XGA-2 and SVGA /A you need to use Ver.1. 50.
The original Reference is based on JDOS and with the original version, option disks for SVGA or XGA can't be read.
The Ref version 1.50 can be commonly used for model 5550-S/T/V, 5570-T/V, 5540-T, 5545-T.

PS/55 Display Adapter IV (512KB VRAM; Optional 512KB VRAM board was available) was used for 5530-T and 5530Z-SX.
Video cable from display unit is very short in its length and it will not reach except the most upper MCA slot where a stock AVE Video Adapter IV should be placed.
IF you are planing to use XGA or any other Cirrus based Video Adapter, you have to use one of lower two slots to which the video cable will not reach. Thus you have to use appropriate video extension cable with D-sub 15pin female on one end and D-SUB 15 pin male on the other end.
38F4816: Cable for Video signal Extension is listed in Service Summary for 5530-Z.

Newly designed 30 series was started with PS/55Z 5530-U. Built-in display was changed from 12" to flat type 13", planar and the BUS riser were also rearranged. 30-T/S provided only 3 MCA slots but newly designed body and planar/riser provided 4 MCA slots though dimension was almost same with the older body. 3 mode FDD (1.44MB/1.2MB/720KB read/write capable) was used for all models. Video cable from display unit is longer than older models so that the cable reaches to the second slot.

5530-UAx IBM 386SLC20 This model was called 30U-SLC.
IBM 386SLC20 Basically same with 30U-SLC but 30V was equipped with Japanese Display Adapter instead of XGA /A.
OS/2 J2.0 was pre-loaded on VJ8 & VY8.
IBM486SLC2-40 V28 & VA8 were equipped with a PS/55 Display Adapter/A.
VX8 & VXB were equipped with an XGA-2 /A.
OS/2 J2.0 was pre-loaded on VA8 & VXB.
5530-V2 was the last 386 class model.

New 386 Planar

U and V planar are almost same. 386SX20 on a U planar was changed to IBM386SLC20 and J1 beside the power connector is shifted beside U1 like V2 planar below.

V2 planar has aux power outlet J22. J10 on U/V planar is not seen on V2 planar. Y3 (CPU clock OSC) is shifted backward.

5530-L was the last model of PS/55 30 series. It's really a nice machine with a 486 class L planar and integrated 13" color display. IBM 486-BL2/66 was soldered on the planar and a ZIF socket for an overdrive processor was ready on the planar. Unfortunately the socket is not PODP ready, it's a Socket 1.

If you have a R planar for desktop 5551-R which has ZIF socket 3, you can make your own "5530-R" which was not released by IBM Japan.

Slot #2 is BVEC and XGA-2 or DBCS D/A /NI-J should be installed on this slot.

I suppose 5530-W uses same riser card.

Front view

4 slot PCMCIA /A can be seen in the left bay where the FDD sits in a stock configuration.

To install 4 Slot PCMCIA Adapter, FDD should be moved to the right bay. This adapter can be used solely in this newer 30 body. Unfortunately I don't have a front bezel to mate with this adapter.

Rear view

Base unit is half-pulled out.

3) Madge Smart RingNode 16/4,
4) Short PS/2 Adapter/A for Ethernet networks with SMC chip.

DSAA 720 is loaded at the HD sled. Thus this machine should be named as 5530-RX7: R planar with XGA-2 and 720MB HD.
