This makes me want to poke a the quad qbus 7220 board that came in the Calcomp branded Terak that I have again. Problem is I have no software for it.
I have some terak-branded disks i dumped a long while ago from a box I found at university, but I think they hold word processing stuff for the exidy sorceror disk drive expansion box, not terak stuff. Just reused 8" disks.
