Ummm, either one or both of us are still confused :-) The C= has two
ports that can be called "expansion" ports: The User port, a 24
connector card edge of the motherboard, and the 44-pin expansion port,
a slot connector soldered onto the motherboard. The former has 17
pins controlled by one (or both?) of the 6522's (the rest is +5, GND,
etc.) and I think the spacing is .156". Jameco seems to still stock
those.
I'm just not doing well today, am I?
The female connectors on devices plugged into the USER port is what I am
after - when I looked these up late last year (I believe in my Mouser
catalogue, but given how well I'm doing today, I just can't be sure any
blasted more) they were quite expensive, my memory says something like $12
a connector. Hence why I was willing to cannabalise broken equipment
rather than cough up for these - as I need about twenty connectors!
I apologise for the confusion, twice over. I don't exactly sound like
someone you want to be sending all your stored Commodore pieces to now, do
I? Honest, it's just been a bad day!

Ummm,
aren't those just .1" spaced contact two-sided card-edges? My
memory may be faulty, but I seem to remember taking prototype boards
with 100 "tongues" per side (what _is_ the proper word?) and using a
hacksaw to cut off the required amount and shape (22 per side?) to fit
the expansion port shape. It would also be a lot easier to solder
to....
Ugh, I seemed to be doped up this morning. I was meaning the connectors
for the EXPANSION port, not game cartridges which, as you say, have
tongues and not slot headers.
The appropriate broken carts I would be looking for would be REUs and
similar for these headers.
