Anyone got a WYSE WY85 KB, p/n 840105-01 ?

A little help, please!

I'm looking for a pic of the PCB showing the chips to help in my research.

Failing that, the part number printed on the PCB (probably something like 99xxxx-xx).

Reason being that I've got a keyboard here with the WY85 layout, but the components on the PCB aren't what I expected, and it's lost its part number label from the back of the case!

Quite surprised I haven't been able to find one by searching - the WY85 Gate Array (840366-01) seems to be more common.
