I can now see that a conversion between the dip and PLCC would be do-able
but as mentioned earlier nasty.
Don't they make socket converters? I would think that would be the easiest way
to go assuming the pinouts would be correct.

yes normally plcc to dip but not the other way around. (cause who would
ever need that) That said the plcc and dip pin out is not a straight 1 for
1 and that makes things a bit messy. That would not stop me from doing it
though. That is making a frankenstein adapter.

I've been looking for some kind of converter but, so far, I've come up
empty. A converter to allow a PLCC44 to be used in place of a DIP is
easy to find, but a converter to allow a DIP to be used in place of a
PLCC44 is rare, at best.
It also occurred to me that signal fidelity (crosstalk,

The PLCC plug portion for an adapter can be had from at least one
manufacturer for $36 US:

Wow at $155 or $125 + $65 for a stel replacement chip.
Like the concept they have of allowing you to rewire the pins and frankly
it would appear the $125 is a cleaner fit if it can be offset in the CS ref.
But hey its not my project so will watch from the side lines.

Now that looks promising! The show-stopper problem with adapters like
Jason found is size. There's only about 20 mm between the circuit board
and the top of the case. I can imagine soldering this plug to a board
that had either the DIP chip or a ribbon cable to connect it to an FPGA
board.
It's starting to add up, isn't it? The only reason I'm considering it
is because I was able to confirm that the Cs tube is alive. If I can
get it working for a couple of hundred dollars and some time I think
it's a worthwhile project and as Bert Kehren mentioned, I'm not the only
one with a

For interest, the prefix refers to the chemistry and the numbers describe the
nominal dimensions in mm.
So:
ML = Manganese Lithium (rechargeable) (3V)
MT = Manganese titanium lithium (rechargeable) (1.5V)
and 621 = 6.8mm diam x 2.1mm thick.
This system is reasonably consistent for coin cells
