BTW, did VMS ever have paper tape reader (and/or writer) support ?
 
Simon.
 

The 11/780 had a 20mA current loop DZ11-C multiplexer so an ASR-33
teletype could be attached and that has a paper tape reader/punch.

Ah, yes, the keyboard that was obviously designed before Health & Safety
or the concept of RSI became a thing. :-)

Mind you, 40 years ago (and I know the ASR33 is older than that), it was
still considered acceptable to use liquid mercury inside toys for children,
so a very different era...

On a more serious note: Thanks, I didn't realise there was a 20mA
current loop option for VAX systems.

Simon.
