Overview (photos from Santo Nucifora)

The 7690 Clinical Workstation is a wall-mounted system with a foldable keyboard and LCD panel intended for installation directly in patient's room.

There's a single 1.44 MB floppy drive on the left side of the unit, hidden behind a door. No hard drive is present.

The unit is based on the PS/2 Model 25 (8086) planar (despite what the announcement letter says) with Model 30 (8086) rev. 04 firmware. The system uses a unique riser card with four 8-bit ISA slots and an RTC circuit. One of the slots is occupied by a special LCD video/touch adapter.

The touch function requires a special driver - available on the 7690 boot and diag. disks. LCD and touch diagnostics are also included.

It was most likely put together by a 3rd party - as indicated by the "Made for IBM" text on the system label.

7690 Planar

Same as the PS/2 Model 25 (8086, Type 2) planar, but with Model 30 (8086) firmware.

System Firmware (POST & BIOS)

Firmware stored in EPROM. Reused from PS/2 Model 30.

33F4498 / 33F4499 - 31 Jan 1989, Model 30 rev. 4, 2x 27256 (U17 / U20)

Riser Card FRU P/N 49F6128, "PRC7248" [P] [P]

B1 CR2032 Battery holder
J2-5 8-bit ISA slots
Y1 14.318 MHz xtal

Y1 There is not enough space around the xtal to lay it flat with the PCB without touching some other component. Be careful not to bump it as that may cause a short circuit.

Back There's a L7905CV -5 V regulator and two SMD caps glued to the back of the riser. This bodge takes -12 V from ISA pin B07 and ground from B10, drops the voltage down to -5 V and feeds it to pin B05. This is necessary because the main power supply likely doesn't have a -5 V rail but the voltage is part of the ISA standard and is used by some cards.

The RTC subsystem on the riser replicates the Model 30 RTC implementation, and effectively upgrades the RTC-less Model 25 planar to Model 30. This is why an unmodified Model 30 firmware image can be used in the 7690 without triggering RTC-related errors.

Touch Panel Driver

The touch panel driver can be found on the 7690 disks. Two versions are available:

LEDTOUCH.SYS ver. 2.4 (7,021 bytes) from the "KQPW" Boot Disk

It's currently unknown what the difference between the two is.

7690 Destiny (from Jeff Karp, original HERE)

The IBM 7690 never made it into field use. Its soldered-in 8086 chip doomed it. Parts for 5000 units were manufactured by IBM, but only a few hundred were assembled and used for development. The beta sites for the Patient Documentation System software (for which the 7690 was designed) used a 1st generation IBM "clam shell" laptop (I can't recall if they were called Thinkpads) with an external touch-screen that was fitted over the laptop screen. The entire project was terminated when IBAX was acquired by HBOC who had a competitive bedside documentation solution.
