Hi Ethan,
I would be *very* interested on one of those for my 11/05 - including
shipping to sunny Australia :-)

I have a couple of the VT1XX 20mA options, if anyone is looking. New in Box.

The current loop is actually "proper" .
There are 3 parts to current loop
1) transmitter (switch)
2) receiver (opto coupler in dec stuff)
3) current source
You will have problems if things don't match. An active transmitter has to
connect to a passive receiver.

There is a DF11-F module that converts TTY to EIA and back again, 2 2-slot
cards, cable,e tc. (Page 4-80 in the peripheral handbook from 73-74). The
handbook did not indicate a specific PDP 11 from this time (05/10/35/40,
etc)
Anyway, the teletype is fine for now, I need to be able to save

I have an 11/05 with ASR 33 for I/O. I am using the M9970 console card to
make the connection. I have loaded papertape BASIC into core (16K) and it
boots up from 000 000 to the TTY, I can type in programs, etc.
Question - I'd like to switch over to a VT 50 in 20ma mode. Not sure if
this is poss
