However, last night I ran into a machine that they DON'T work with, for an odd reason

I recently picked up one of these gadgets from DealExtreme, same chip family as above.

It won't work with an 80-conductor cable at all, but does work with a 40-conductor cable (a short one, perhaps 10" long; I didn't try a longer cable).

Weird. But useful.
