Is this the RS-232 module valled "VIC 1011A" which connects to the C64 "User
port"? If so, I found one in a box of Commodore stuff I picked up this
weekend... (Sorry, I don't think I want to part with it just yet, and it
would be a long way to send it anyway).

If anyone has some info on this device, it would be appreciated.

I tried to look inside, however after removing the single screw from the bottom,
it still seemed to be glued together, and I didn't want to break it.

I'm guessing that it's just level converters for a "bit bash" serial port... If
so, it should not be hard to cook something up yourself. Here is a page giving
some information on rolling your own C64 serial port:
