Subject: ASR-32 Usable as Terminal?
<SNIP>
I just realized, *after* bidding, that this TTY on
eBay is a 32, not a 33.
Oops. Since it uses baudot code instead of ASCII and has a rotary dialer
on
its CCU, is it useless as a terminal for a PDP-11?
What would be required
to
make it useful for a terminal?
I'm thinking that I should cancel my bid. I want a TTY solely to have a
period terminal for my PDP-11/20. :-/
Yes, I have read the following in the "vital poop" thread:
One suggestion is to put a PIC between the system and the 33. Let it
translate the baudot to and from ASCII. We made a "driver" to do this very
thing many years ago when using a model 28 with an Apple II and it worked
fine as a printer. VERY NOISY - so bad we wrapped to mattress from a camp
cot around the thing to try and muffle it. Since I already had the model 28
it was a cheap solution.

Before you spend big bucks on ebay
----------------------------------
A Model 33 has a four-row keyboard (not including the space bar).
A Model 32 has a three-row keyboard (not including the space bar).
The 33 is ascii, and the 32 is baudot.
You cannot (prctically) modify a 32 into a 33.
