DRAM!? In a PET?! That is crazy talk! ;) There was
never even DRAM in
the C64... Although I believe the SuperCPU used DRAM memory, but that
was third-party.

Say what?
AFAIK all their stuff used DRAM except for the first two 8K versions and the
oddball VIC-20 (or VolksComputer as it was known in Germany to avoid the
connotations of a certain homonym of VIC, pronounced 'fick' in German...),
which they probably produced to use up 2114s left over from the old PETs ;-)
I've never owned or seen any 8K PETs other than the 6540/6550 version,
but as Ethan says there was a 2114 version with industry-standard ROMS;
=16K units were all DRAM AFAIK. Once DRAM caught on it
didn't make
economic sense to use SRAM in any quantity; look at S-100 boards.
