I've had at least one 8271 fail, although I can't quite remember the
error. I seem to remember it just hung the machine up.

I also had one machine that had spent its entire working life as an
Econet station, until I tried to fit the disc interface from a dead
machine and found one of the pins of the 8271 socket didn't actually
go into the hole in the motherboard, it was bent out sideways. It took
me ages to find that, I made the link by scratching the lacquer off
the PCB trace and putting a blob of solder on.
