Picked up an IBM EduQuest 40 from Goodwill. Freaky machine, it's a mutant
IBM PS/2 Model 25, more expansion slots and it looks like it has a larger
monitor. It's got great support on IBM's web site, if you can find it. IBM
seems to like the K-12 crowd.
Also picked up a DEC VT-420 terminal for $1. Seems to work but I don't have
the video cable for it.
Happy Hunting!
