I was
working for Hazeltine terminals group at the time, one look
at the
1400s and I left. There were a few things about it that suggested
with
better firmware it could be nice but didn't happen.
That makes me wonder if new firmware could be created now? What uP
did it use to control the electronics?
Its my first Hazeltine for my collection. And no, I don't expect I'll
actually be sitting at it doing coding :-P. -Dave

But it (the *1510*)
was indeed built around an 8080. :)
And sadly, it is quite dead...powers up and says "BEEEEEEEEEEEEEEP!
*" interminably. Anybody got schematics?
