Hello again, Mate ... you forgot to mention the tractor!
Believe it or not,
this was the most successful British computer ever made (in terms of numbers sold, that is).
... it also tends to see the greatest activity on eBay (oh, the Magic of the Marketplace)!
To be honest, computers are only (or have become) my scene because "they" won't let me
refurb medical equipment!
But, as you know, I enjoy lifting the lid on
all manner of kit ... but old computers, especially. They're like boxes of chocolates, you never know what you're going to find!

"Classic Comms Receivers" may be all very well, Dicky, but as a rule you can't
program them, can you? Surely that's the beauty of computers; there's both the hardware
and the software to play with. Not forgetting, of course, the
firmware (which is especially the case with the BBC Micro).
