I don't have a BBC and have not done a great deal with them. I do remember, at college, working with a BBC with 8086 (I think or maybe 80186?) second processor with 'C' language. That was an absolute pig of a system but did work. Do any of these second processor systems still exist, or were they so rare that they have gone?
At work, a bit later, we used to curse the BBC's when backing up softare from the communication aids of the day. They backed up / restored via serial interface. It most always took a while to do a backup as the process took the best part of an hour and invariable crashed at forty five minutes. It's quicker these days with PC's and USB but, as software has now got more complex on the aids too, it can still take a while. Glitches still exist now and then too!
I did my early interface tinkering with a VIC20, which I still have. They use the 6502 like the BBC and 6522 interface which was useful as readily accessible.
