Hi Y'all,
I just popped open an ASR-33 I picked up a few weeks ago. The tty ran
OK in local mode in the store where I found it but in shipment to me
something happened, it now free runs (runs free?). Maybe it's a loose
connector.
In the electronics bay on the right hand side, there's a printed
circuit board that runs from front to back. It's definitely a power
supply, and probably also an RS-232 to current loop converter. In
front is the line/off/local switch, and in back are several large
Molex connectors. I was surprised to see this printed on the circuit
board:
MITS INC
TELETYPE INTERFACE BOARD
REVISION 0
COPY RIGHT 1976
Does anybody know if this the Altair MITS? The date seems about
right.
Was it common to produce custom internals like this for teletypes?
Anybody have the schematics for this board?
Thanks,
Brian
