Hi List,
So a good friend of mine recently resurrected his childhood 286 Wang

Hi Pontus,
No, you probably didn't miss anything. I have several students working for

Thanks, Paul

some disks (and I can deal with restoring the Persci drives), it comes with
no documentation. I do want to restore it to working condition.

If you can write your own code, usually a simple write and read
sequence will find a dead RAM. Just write 0xFF to a location
and expect to read it back and then 0 and read it back.
You write it so that it will stop at the bad RAM location and

once again I have high school kids doing things I can no longer do. I'll go
