I've got four known-good spare TMS2532s left, but I don't really want to part
with them (I keep them as spares for other machines).
If you find anywhere that's selling HN462532Gs, I'll take a few.
I'm not sure if I've mentioned this before, but if anyone on cctalk/cctech
wants any EPROMs programming, I'll do it for cost-of-postage only, as long as
new EPROMs are provided. I've got a PREPROM-02aLV from <www.elnec.com>. If
it's on the device support list and doesn't need an adapter, I can program
the chip.

Painful experience?
Another one - EPROMs that have been installed in the socket backwards in a
device that posesses a very big PSU tend to glow white-hot then die.

Got any spares left?
Later.
