Pictures are much appreciated, but of course I'm also interested in the ROM
image and the connection diagram of the plugs. I do have a ROM image of such
a cartridge, but without those plugs all the port tests fail. I think someone
said the program even stops at the first test that fails (just like my C128
cartridge), but the copy I have does not do this. Maybe someone (Nick?)
patched it to run without the plugs?

BTW, VICE 1.9 runs the ROM quite fine, but it also stops at the ROM test,
just like my 2nd PAL machine (maybe I should try an older ROM set). Use the
menu, or this command line to start it:
x128 -extfunc -extfrom 325099-01.BIN
