The PS/2 E (Model 9533) FAQ
The following information is culled from a variey of posts I have made
to Compuserve on this subject.
The PS/2 E (model 9533) system unit has a PS/2 model 35 motherboard.
486SLC2 25/50 MHZ CPU, 4 MB memory soldered in, 2 sockets for IBM PS/2
style SIMMs (2,4 or 8 MB), to a maximum of 16 MB. IDE disk drive, only
enough room inside for a laptop 2.5 inch IDE drive. XGA-2 video on
motherboard. One ISA bus slot, depending on the model it may contain:
- Nothing
- An IBM ISA Token Ring 16/4 adapter
- An IBM ISA Ethernet adapter
- An IBM 3270 emulation adapter
- A special adapter that has 4 PCMCIA Type 2 slots
(2 accessible from the front, 2 from the rear).
MEMORY:
There are 2 slots for memory, you can plug a combination of 2, 4 or 8 MB
SIMMs into them provided that the total of the SIMMs and the onboard 4
MB memory does not exceed 16 MB. "Generic" or "industry standard"
memory will not work- it must be "PS/2 style" 70 ns parity memory. It
uses the same memory as other PS/2s of the same vintage- if in doubt,
ask the supplier for memory for an IBM PS/2 model 56 or 57 or 76 or 77
(8556, 8557, 9556, 9557, 9576, 9577). These were very common models.
HARD DISK AND DISKETTE DRIVES:
It'll accept any 2.5 inch IDE laptop drive, provided it is not too
"high" (thick), as it has to fit under the diskette drive. If the drive
is over 512 MB you will also need "Disk Manager" or "EZdrive" or similar
software in order to be able to access more than 512 MB of the drive.
(The PS/2 E does not have "large disk" or "LBA" support in BIOS).
A driveless model can be expensive to build up. I went through the
exercise because I got the unit itself very cheap. You need an IBM
Thinkpad 720 diskette drive and a PS/2 E cable (you can't build one,
it's a ribbon printed circuit) to attach it to the motherboard. The
hard disk drive is easier- I used a generic Quantum drive- but the IBM
cable for it is a good idea, because it has the right power tap-off.
Laptop IDE drives have the power wires on the same plug as the signal
cable, but the 9533 is "desktop" IDE where the power is separate. The
IBM cable splits out the power wires to a special connector from the
power supply. I couldn't find a part number for the diskette drive
faceplate to replace the blank one, so I carefully cut a slot in the
blank plate.
BUS:
The machine has a single ISA slot. Some models came with the slot
empty, some with a Token Ring network adapter, some with an Ethernet
adapter, and some with a 4-slot PCMCIA adapter. Your upgrade options
will depend on what you have. With the PCMCIA adapter, you should
consider PCMCIA sound and CDROM adapters. Otherwise, you can do
something like I did with mine: I installed a Sound Blaster 16-SCSI
adapter. The CDROM drive cable ran out of the back of the case to the
drive, which I put in an external box with its own power supply. It
sits on top of the PS/2 E. Note that the internal power supply in the
PS/2 E is very limited capacity. I had to disable the internal speaker
amplifiers on the sound card, it was hanging the machine when loud
sounds were played. I now use external amplified speakers. Most recent
sound cards no longer have internal amplifiers anyway- people prefer
external amplifiers to get more power, and control over
volume/bass/treble etc.
DISPLAY ADAPTER:
The on-board display adapter is an XGA-2, for DOS/Windows you will need
the XGA device driver diskette (latest version is V2.12, in the library
somewhere and on IBM's file site).
DIAGNOSTIC AND SETUP DISKETTES:
It is an ISA bus system and, in common with IBM's other PS/2 ISA bus
systems, does not have a Reference diskette. It does have a "Starter"
diskette, an image of which is in the library here. There's also a
"Utility" diskette which contains, amongst other things, management
utilities and drivers for the 4-slot PCMCIA adapter that some models
shipped with.
Here on Compuserve, look in Lib 2.
Title : PS2EST.DSK
Keywords: IBM PS2 E STARTER DISKETTE REFERENCE
Starter Diskette for the IBM PS/2 E. Version 1.0. This program will
need LDF.COM to make a Disk Image. LDF.COM will be found in the same
library. Run it and follow the readme instructions.
