Ugh! 9 pounds each? I need to buy around 90 of these.
The P112 was designed with a 32-pin socket for the boot ROM, so a 29F010
(which I found for a good price) looks like it would work as long as
pins 1 and 2 are grounded. I'm not quite sure yet. Now to find
whatever old version of Protel Dave Brooks used. I should be able to
make the change by directly modifying the gerbers, I guess.
I'm going to go to bed tonight rather annoyed. Damn chips going out of
production then the price goes sky-high.
There seem to be quite a few 28F256s on eBay, you might be able to get
the required quantity there. One is listed as "more than 10
available"...I just bought some parts from that seller ("eedesigner"),
he seems to have HUGE stocks of things.

Farnell have several 28c256 chips which are pin compatible.
