And thusly were the wise words spake by Ethan Dicks
 Also, if it has the 320008 motherboard with working 6540 ROMs and
 6550 RAMs made by C= as opposed to later off the shelf 2316B ROMs
 and 2114 RAMs... 
 I know C= made static PETs with 2316s and 2114s, but I've never seen one.
 All the chiclet-keyboard PETs I've personally laid hands on had 6540s and
 6550s.  Does anyone have any sort of stats for how many static PETs were
 made after the switch?   And didn't C= offer 8K dynamic PETs for a short
 time?  (16 x 4Kbit DRAMs)
  
 
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.
I can't find any schematics of PETs on 
zimmers.net (used to be one funet)
that use DRAMs...

  In other words, about how many of the later static
PETs were made compared
 to the earlier ones?
