I dug out the boards that I have to dump the eproms, and a while back put up what I had
for schematics on bitsavers.

But, it was glacially slow! I did have some memory that was likely a little slower than

Well...considering the era, it wasn't too bad. By today's standards, yeah,
it's pretty darned slow.
Vi starts up pretty quick, even with a couple of terminals running on it. It runs rogue
pretty nicely, quick enough for multiple people to play it at once.
The machine has 7MB of RAM, which really helps. Without additional RAM, there's
only 1MB on the main board, and running it with just 1MB makes it incredibly slow. There
isn't any external cache.
It's fun to fire it up and just relive the days when I was on cloud nine to have my
own personal Unix workstation that I built myself from parts.
