The last PET 2001 with the chiclet keyboard I bought
cost me $35.
Clearly, there are bargains to be had. $150 is a fair price though.
Shhhh!
I wanna find another Cameron that'll give me $900!

We still seem to get them offered to the museum in healthy numbers - including
the chicklet models (and once in a while one of the blue-fronted ones, which I
believe are the earliest).
I've never tried actively seeking one out though as there's been no need.
Finding one that works seems to be the difficult bit - I don't think I've ever
seen one which hasn't required some form of TLC inside. Nasty, clunky,
horrible things they are ;-)

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

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...

What do you call 4164s? (though the C-64/e switched to a pair of 4464s).
The VIC-20 was always static, though (5K of 2114s).

Thank-you.. You are very much correct in saying there were dynamic RAM
PETs...

Over here, the original 2001 (with the chicklet keyboard) was succeeded
briefly by a similar model still with SRAM but with a "proper" keyboard,
and that was succeeded by the 3000 series and then 4000 series, both of
which used 4116 DRAMs, with model numbers 3016, 3032, 4016, and 4032
according to whether they had 16K or 32K. Almost all the 40-column PETs
I've seen from around 1978/79-1982 had 4116 DRAM.

What are you talking about here? I've never seen one that didn't use it,
almost all of them being 4164s or variants, except for some of the very late
boards that went to a somewhat denser chip...
