That's annoying. All of my C64s are the 8-pin variety. (I've actually
been selecting them that way. :) ) Hopefully the Data 20 cart doesn't
suffer the same problem as the Commodore cart.

Well, it does have two 5-pin female connectors on the back, which would be
for the video. The other connector looks like the typical power connector
for an external modem, but I suppose it could be a composite out for use
with a weirdo cable.

Time to open it I suppose. <s>
