Well, Allison, you're right about the Esprit, since it didn't come around
until the very late '70's, but it was my choice at that time because (1)
there was no significantly cheaper terminal available, and (2) it emulated
the Hazeltine 1500, LSI ADM-3A, and one other which I don't remember, since
I probably never had occasion to use it. The basis for my suggestion that
the terminals best for CP/M is my experience that the ones I listed and the
Visual 50 (also with several emulations) were the ones we had the fewest
compatibility issues under CP/M. Various software packages had to be
configured specifically for whichever terminal was in use, and being "close"
generally led to trouble.
The early video boards with 16 lines of 64 characters weren't supported by
most software vendors at the time. Only after the popularity of the TRS-80
(1978) became a factor did 16x64 become useable with standard CP/M systems
and software. Of course, one could write one's own drivers, but that was
not a popular solution for most users.
Who built that VDM-1? Was that not a part of some vendor's "set" of boards?
