Is that a 64 vs. 64C issue?

The cart looks to be cemented together; I'll try a lot harder to find
the docs before trying to disassemble it.
In the mean time, I found a "SID Symphony" cartridge on eBay, which
was interesting... what started this whole odyssey was that I have
one of the "Dr. Evil" ones made by Kent Sullivan before CMD started
distributing them, and it doesn't work any more. Kent's had a 9V
battery inside that you had to change every so often by opening the
cartridge; apparently the CMD ones (like I got on eBay) don't. I
almost destroyed it trying to open it before I realized that :(
but anyway, I heard Dr. J's amazing stereo SIDs again tonight for
the first time in years. Absolutely unbelievable.
I'm still looking for documentation on the carts that Mark Dickenson
made, if anyone happens to run across it (I did find all the docs for
the "Dr. Evil" version of the SID Symphony). And thanks for all the
suggestions.
P.S. The second SID maps in at $DE00 on all three carts.
