It seems to have mostly computer problems for now (and a missing 400$ step attenuator later). It gets stuck in the loading screen, so the previous owner tried replacing all the RAM chips. That only made it worse, so I just reverted to original RAM chips and now at least it shows something again!
Next I'll try and listen on the pin headers on the main board, to try and catch some debugging messages.
Hope I don't have to take too much of plunge into HF voodoo, yig oscillators and weird filters to make it work...
