The 7496 Executive Workstation can be considered an all-in-one computer
system, most likely designed for the healthcare sector.
The machine is build around the PS/2 Model 30
planar and riser.

Same as the PS/2 Model 30
(8086, "P-PLANAR") planar.
System Firmware (POST & BIOS)
Firmware stored in mask ROM. Reused from PS/2 Model 30.
61X8940 / 61X8939 - 05 Feb 1987, Model 30 rev. 2, 2x 27256 (U17 / U20)
Riser Card P/N 61X8864
Same as the PS/2 Model 30 (8086)
All three card-edge connectors are populated, but since the chassis has
space for two adapters only, the top connector is covered by a label saying
"DO NOT USE THIS SLOT".
Sony Trinitron Character Display
Model No.: CPD-9090
FCC ID: AK896ACPD-9000
It seems to be a slightly modified CPD-9000 (see HERE).
The monitor supports both digital and analog video signals. The input method
is selected manually by a switch on the back side of the unit (hidden behind
If the monitor displays a raster when powered on, but doesn't react to a
video signal from the base unit, make sure the mode select switch is set to
"ANALOG" to match the MCGA video output. If the setting is correct, try
moving the switch back and forth a few times to ensure proper contact. If that
doesn't resolve the problem do a visual inspection of the signal cable and test
it for continuity.
The "RGB IN" connector is Honda VTR type EIAJ-8 (some info HERE).

The 7496 Executive Workstation is another piece of the 7690
Clinical Workstation. While the 7960 hung next to the patients near the
beds, the 7496 sat in the crowded nurses pits - thus the relatively well sealed
units and small stature. The labels on the bottom of the the units give the
clue - they were printed by the same company that did the conversions, and that
company was not IBM. This was done for a relatively large trial by one of the
healthcare providers - maybe Spectrum? I found a link a couple of years ago
describing the system, but it seems to have disappeared. It describes the trial
having 1000 units, but was ultimately not a success and killed off. I do not
know what the central server was - perhaps a mainframe?
