Pretty certain the system I remember hearing about was
a 990. There indeed
a couple of terminal emulater cartridges for the 4A. Kermit was ported to
the 990 and the 4A as well, but that would have required an expansion
system with drives, which this file server setup was apparently intended
to avoid. Little fingers, I guess.
I used to work at TI, and for a while we used a TI 990
minicomputer. I can't remember many details (we replaced
the 990 with a MicroVAX II about six months after I
started). I remember using TI914 terminals, which were
block-mode terminals. I don't remember the name of the
operating system, but I do remember the OS was not very
secure.
There was a TI-developed 914 terminal emulator that
was widely used in TI. Long after the 990 systems
were gone the 914 terminal emulator was used to
connect to the IBM mainframes.
