If the original machine boots, there are many
possibilities. I once
did a linkup with a system with NO serial or parallel ports (and an
utterly incompatible with anything floppy setup) by bit banging an LED
on the console and picking the bits up with a phototransistor connected
to some parallel port pins.
Chuck,
I hate to think how long it would take to transfer a 400MB drive using that method... Of
course if the data is valuable enough...
