Another hurdle for the 5620/630/730 lines of terminals was when I tried getting software support. Teletype being a mostly a "dumb" terminal manufacturer never considered them more that a way to have multilple 80 char x 24 line terminals on one display. I had difficulty in conveying to them that it was a computer in its own right and you could program it. The marketing was probably just as limited in scope. Another blow for the BLIT portion on the terminal came when you cound get an external cartridge for the 730 that turned it into an X-terminal. I got mine in 1991 and then rarely used layers after that. -B
