Your naming isn't right, although the story otherwise is accurate.
The Jerq was the original name for the 68K machines hand-made by Bart. The
name, originally coined for a fun demo of the Three Rivers Perq by folks at
Lucasfilm, was borrowed with permission by us but was considered unsuitable
by Sam Morgan as we reached out to make some industrially, by a company
(something Atlantic) on Long Island. So "Blit" was coined. The Blit name
later stuck unofficially to the DMD-5620, which was made by Teletype and,
after some upheavals, had a Western Electric BellMac 32000 CPU.
If 5620s were called Jerqs, it was an accident. All the software with that
name would be for the original, Locanthi-built and -designed 68K machines.
The sequence is thus Jerq, Blit, DMD-5620. DMD stood for dot-mapped rather
than bit-mapped, but I never understood why. It seemed a category error to
me.
