Hi, all:
I've got a DEC PDP-8/I with the typical current-loop TTY interface. I also
have an ASR-33 teletype. The teletype, though, isn't a DEC-modified
version; it's got a Data General card in it instead of the 4915 card DEC
installed in their teletypes.
I'm Data General ignorant, I'm afraid. :/ So here's my questions:
-Do your typical Data General systems use a 20ma current-loop to talk with
ASR-33s?
-What's the pinout for DG/Teletype connections? Is it something that can
be made DEC-friendly by simply wiring a different connector to the DG
TTY's cables, or are the differences in signals more extensive?
-If the solution isn't that simple, does somebody have a 4915 card they
wanted to part with (or a schematic of one) (or a DEC-outfitted ASR33 they
wanted to trade for a DG-outfitted ASR33 <g>)?
Any help appreciated. Thanks!
-O.-
