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.
