The 6502 emulator was written in Turbo Pascal on the PC and was written 
in such a way to support further hardware emulation. We wrote it such 
that each machine cycle was correctly emulated at the correct (1Mhz) 
speed. This left time spare and we intended to use this spare time 
between cycles for other hardware emulation to be carried out and thus 
emulate the system at the lowest possible level - this is how the 6845 
was almost completely emulated. However due to lack of speed of machines 
at the time (20Mhz 286) the amount of work to emualte all BBC hardware 
meant pascal was unsuitable so we shelved it and considered maybe 
someday porting it to 80386+ assembler. Maybe this would be a good time 
to start?
