I am suprised a sound sampler used the printer port -- there's only 2
bit of input (the ACK line). Why not use the user port?

It's brought off-board. It's linked to a 24 pin Blue Ribbon connector
(looks like a GPIB connecotr, but isn't the same wiring, of course) on
the back. I will certainly make a cable to link it to a printer...

Ah, so there is a loader program. I will dig about on the 'BBC Lives'
website, I can't believe there's nothing suitable there.

If you want to transfer individual files, there is a kermit for the beeb
(and for that matter for the ACW's 32016 side...). Kermit may not be
efficient, but it's available for anything....

Ah yes, that stupid quincuncial DIN plug. Fits both ways up, only 1 works....
