Good.

That's a significant price difference (EPROM vs. EEPROM).  We will use
the EPROM.

Earn brownie marks for yourself.  Mention it on the Design Web.  The
only person who actually reads the Design Web is Malone and he'll
think you're being helpful.

As you stated, it may be good news in disguise that Active Electronics
is out of Malone's IR emitters/detectors.  Did you ask how frequently
they restock?

I have never seen or heard of an actual transistor socket before.

Not necessary.
