Re:You really had to Bang on those things. (Score 1)

I cut my teeth on a PDP-8/I (rack-mounted, 18U) wired to an ASR-33 teletype. You used to boot the beast through the paper tape reader using a hand-duplicated paper tape. I later ran a lab with 32 of these things hooked to a timesharing PDP-8. Had to come in early every morning to stoke the fire under the boiler...

The other thing these were good for was printing program listings overnight. Come in in the morning and fold up 35 feet of a 40-foot program listing (think about it). Trouble was, teletypes were designed for intermittent duty, not pounding away all night. We provided job security for many a Teletype service engineer.

UM used to run a mainframe timesharing system called MTS on their '67. I wasn't at UM but our campus ran it too. Yes, it had TTY support.
