I am quite sure you're capable of tracing out the schematic of something
like that. It sounds like all the chips, and the bus pinouts are known,
which will let you tie down and name a lot of signals.
I've found that for things like this it takes less time (and is less
stressful) to trace out the schematic than either to try and find one or
do battle with the companys 'customer service' who rarely will supply

This reminded me of another device I have. It calles itself an
'InterView'. I forget who made it, maybe Trend. It's clearly some kind of
protocol analyser. Alas it was dropped by an idiot long before I got it.
The result is that the card cage is distorted (but the PCBs are all
intact), the CRT has left its tension band (which scares the heck out of
me!), and the cartridge tape drive (DC100-size tapes) is in many bits.
Another project for a rainy day...
And then there's the TDMS5. TDMS == Telegraph Distortion Measuring Set.
This is sort-of the same kind of instrument for 5-bit teletupe lines.
It'll send a given character repeatedly, send the Quick Brown Fox
message, display the incoming bit transitions on a circular-timebase CRT,
test polar relays for transition time and bounce, and so on. This thing
is stuffed with valves. Fortunately I do have the service manual with
schematics and layouts for that one.
