I've been using one in an XT for a couple of years now. It seems to be
reasonably built, and so far it works with all of the common EPROMS and
PALS that I've used with it.

I also noticed mine getting warm after a while. It appears that on power-up,
the hardware comes up in some uninitialized random state. I found that
by running the IOCHK program that comes with the unit whenever I boot
the machine, it initializes it properly, and it no longer gets warm.
