Anything custom in it? Or just a lot of 74S/AS/F?
No customs. If I can dig up a reasonable resolution camera I'll shoot some
board pictures (they're big)
Considering how many superminis CHM has in the collection, there is a disappointing
lack of software and documentation for them here. I'm sure it was the usual thing
where
the hardware sat in storage until someone got sick of looking at it, and they never
bothered to save anything else. That was how I ended up with all the Ridge boards,
they showed up at a scrapper and had no idea what they were.
A rear shot of the CPU cabinet would be nice to see. I forgot that it was quite common
to attach a graphics terminal to them through a DR-11W style dual 40 pin interface.
Ridges were used a lot for LSI design with the VTI cad tools.
It would also be interesting if there is an Ethernet interface on it.
The 1985 and 86 processor and hardware reference manuals in pdf/ridge on bitsavers is
about
all that ever existed on the hardware.
