outstanding effort Brad! well done.
I like how you chose to do one of the less well known PDP-8 models too - is
that model special to you?
Edusystem-50 (TSS/8) was developed to run on that model. It took a lot of effort
at the University of Wisconsin to have DEC ship us an 8/e instead, since by that time the
8/i was pretty long in the tooth. It also let us add an RK8-E later on for secondary
storage, which is reflected in the UWM monitor code that is on bitsavers. Adding the RK
made the system self-hosting. You would take down TSS/8, bring up OS/8 and rebuild the
system.
