Several of us (including myself) don't have space to set up another
machine, like a modern PC. You suggested a KVM switch. As I understand
it, this is a device that switches a single keyboard, monitor and mouse
between 2 machines.
But most, if not all, only work for machines which take PC-like keyboards
and VGA monitors (forget about the mouse, OK :-)). Which means it
wouldn't svce any space here becuase none of the machines on or around my
desk use such peripherals. So a KVM switch couldn't be used to share one
of the monitors and keyboards with the new PC that runs imagedisk.

Oh, I probalby could, but I like to use the original keyboards on my
Anyewy, if I am going to go to all that work, I might as well design a
disk imaging device, which certainly wouldn't use an 8272 controller. If
I used a single chip, it would be one of the WD ones (which have a much
more useful read track command). Or I might just make something like a
Catweasel and grab the transitions on the read data line from the drive
an analuse them in software later.
