I don't try to build it, I just suggested it.
And yes, the x86 machine IS much too fast. But if I let it do some
nonsense calculations, one can slow it down to any speed wanted. So it
is possible(IMO) to do a much better timing than the original apple ]
[ with its fixed clock.
PS: the data to the disk drive is clocked at 250kHz, not 2 MHz.
