The BBC Machines are as big a love as the Amiga to me...
I've still got quite a few expanded real Hardware systems, which I've repaired and kept going.
The Beeb was very influential for it's day and if anyone is interested BeebEM for the PC and MAC is available, PC by Mike Wyatt - MAC by Jon Welch. and these guys work as hard as Toni to provide a superb emulation platform.
Agreed the addons were expensive but copro Elite is still one of my faves
and the emulation platforms let you emulate just about every addon / expansion that was available.
Go on Guys give it a Go.
