References like that prove nothing.

It was a telly, it was flying back - thanks to, imagine it, a
flyback transformer.

I said it is more likely he has no education. (Unless you have a low opinion
of Cambridge :-))

It has the ports. So, you connect a teletype or VDU to it. I doubt BAH's stove has a
keyboard input and a display or printer connection..

Retrace and flyback are equally acceptable.

I can see you now. The kind of manager who delights in belittling ppl. You have
all the hallmarks. A total disaster for any company employing you.

Actually, it may not have any ports. The PDP-8 didn't even really have an
I/O instruction. One of the 8 codes was a NOP as far as the CPU was
concerned. You would decode this externally and do the I/O operation with
external hardware.

Most PDP-8s had a current loop interface built onto them for the paper
tape reader.
