Hi
I did some more searching and they do have a 32 pin dip listed
on a catalog page but it doesn't show on their web search.
On page 17, they have:
Part# 242552CG
29C512-12
DIP-32 5V
$5.25 single
$4.25 10ea
This isn't in their current paper catalog but does show on one of
their reference catalog pages for flash memory.
It should be worth a call. 1-800-831-4242

Yeah, I need dip. As for redesigning the P112 from the ground up, that's
not out of the question. This hassle with tracking down parts going
obsolete has made me ponder that. Fortunately the super-io and cpu are
still being made and don't appear to be going away any time soon.
Hi
Why not use a 29C512 and just tie the extra address?
Jameco listed at $2.39 but not in dip.
Not to speak for Dave (who's more than capable of speaking for his own
damn self), it probably needs to be DIP. It is one of the kit
components the end-user solders in (well, you solder in a socket, then
snap the chip in the socket, but whatever). I believe redesigning it
for a PLCC or other surface-mount package would require a pretty
significant board redesign on Dave's part.
Not to mention the additional benefit to having it in a DIP package: it
means it can be swapped out if desired for different firmware (although
I don't know of anybody actively doing it with the P112).
