Question regarding the PDP-7 (see
http://www.classiccmp.org/pipermail/cctech/2003-June/015291.html)
I am working on the Teletype (KSR33) and wondered if anyone has (a
reasonably priced) one? ASR is a small plus, but not neseccary.
I have a pathetic budget for this (?9, $12-ish) project, but I could
probably scrape up some dough if needed.
I live in Norway, so Europe is a plus. We have the 220v-115v converter
built-in to the stand.
And, does anyone know about the interface of the thing?? Is it RS-232
compatible?
Love, Piece, and Understatements

If you've got one that you're working on, why are you looking for another
complete Model 33, rather than spare parts/manuals? These machines are
not difficult to repair...
And, does anyone know about the interface of the thing?? Is it RS-232
compatible?
Unlikely (but I guess possible). Most of the Model 33s used with
computers have a current loop interface, either 20mA or 60mA. Converting
that to/from RS232 is an interesting little project.

As I recall, the TTY 33 had a 110 baud modem built in. I don't think
you had to order the modem as a separate thing. The other comment
about a current loop interface sounds familiar, I presume that was
between the internal modem and the controller box.

Understatements go without saying :-)

As an option.
I have one ASR-33 with (along with a touch-tone keypad for dialling)
and one without (fitted with the DEC reader-run relay and a six-wire
console cable).
The one with has it in the pedestal. It *fills* the pedestal.

I take it yours is not working

No it will be 20ma current loop. Conversion to RS232 is quite trivial we
have a homebuilt box which does that. Let me know if you need teh
schematics.
