Leaving out a lot of detail, when it was time to commercialize it, Teletype came in and studied it. They they made a bunch. Later, they were pressured to convert it from 68000 to BellMac32. But fundamentally it's a Research artifact. -rob On Thu, Jul 4, 2024 at 8:04=E2=80=AFAM segaloco via TUHS wr= ote: > > I suppose this question is best directed at Rob or Doug, but just might a= s well ask at large: Given AT&T's ownership of Teletype and the involvement= (AFAIK) of Teletype with other WECo CRT terminals (e.g. Dataspeed 40 model= s), was there any direct involvement of folks from the Teletype side of thi= ngs in the R&D on the Jerq/Blit/DMD?
