Does anyone here use electronic test gear for repairing these old machines? I am trying to hunt down information (manuals, schematics, ROM images) on a device made by Micro Circuits called Boardwalker - models 101 or 103. The group of techs I keep up with have tracked down a few sets of ROM images (up to V2.50, Library V1.60), but no one has found a manual - so far. The device is handy in that it can test TTL and Eproms (up to 24 pin devices) in circuit by comparison to the built in library and it appears that you can add to the library too... Thanks!
