At this distance?  I'll have you know I've got all myt BBC Micro books
onthe shelf behind me, and if we ever have two working bikes capable of
doing over 70mph, I'll have some BBC micros up here too.

RS423 on the Beeb, closely related to the RS422 used on Macs (although
much slower using the IC on the Beeb which could only manage 19200 bit/s
at a pinch, compared to 920000 bit/s that the serial IC in every Mac can
manage).

Mind you, when you're used to reading in programs at 1200 bit/s off a
cassette player, 19200 bit/s is mega high speed.
