Thanks for the announcement. I think I may have a
current-loop to RS232
dongle somewhere around here (or I could make one...)
OR,
the 5150/5160 "Asynchronous Communications Card" supported both RS232 AND
Current Loop. Yes, the 8250 won't handle current high speeds, but how
fast are you going to drive an ASR-33?
OR,
find out just what they actually have in mind!
Do they want an ASR-33, because it is "RETRO" looking?
Or are they looking for a printer that can survive the kind of abuse that
kids are capable of? (YES, that is a MAJOR issue for Exploratorium)
Is it expected to be returned intact?
WHY are they looking for an RS-232?
Because it is easier to interface to than current loop?
Or, because they want something that can work at the end of a mile of
wire?
Are they looking for ASCII? or "Baudot" (inaccurate name)?
