Hi! I have a display and controller card out of a Compaq Portable III, the 286 'lunchbox' model. This was also used, identically, on the Compaq Portable 386 from what information I have available.
Mine is marked as an Assembly # 000932-001, with serial and revision numbers unmarked. A sticker at the bottom reads "M1154-001", and it is also identified elsewhere across itself variously as "SCH 000933" and "Board No. 000934-001 AW Rev E Fab Rev [E]". Two barcode stickers also are extant on its underside; one is a standard Compaq part number sticker with the number " 49054 " above the barcode; the other is wide and a sort of dark marigold yellow and reads " *9BT3E10FL* " under its barcode. A light yellow sticker immediately below the yellow barcode sticker says "REV K" in OCR-ish dot matrix printer type. There is also written "TP TPB-J.V0" in trace copper in one spot, with the text "8905" in silkscreen underneath.
Hopefully this is of some use in identifying the board until I can get a decent set of photos uploaded.
Connections to the mainboard consist of what appears to be a 50pin ribbon cable, plus a second 10pin ribbon cable reminiscent of a COMport header dongle. The only other connector present (besides a single two-pin jumper within a shielded area of the card, from which the shield's top is easily removed is an unpopulated 3pin jumper footprint just outside the shielded area.
Does anyone know how this communicates with the mainboard? I suspect that it's just ISA-8 with a nonstandard connector but I'm not sure.
