It sounds like you're referring to the Cardco 'Cardboard/3s' expansion
interface. Does it have a reset button and a bank of seven switches on
it? I have one, in the box with the manual. It also has CB/3S along
the outermost edge on the bottom side of the circuit card. Nifty little
gadget, as it would even allow me to use the 'Programmers Aid Cartridge'
with the 16k memory expansion.
One has 3 slots and a fuse and is marked as 'Cardboard/3'. It must be a
cheaper model than the 3s. The other one (made by PTI) has 3 slots, 3
slide switches, and a fuse. I neither one has a reset button. I can see
That the one with the switches should allow selection of which cartridge
to use, but it is not clear to me how the Cardboard/3 is supposed to work.
There must be some real voodoo needed to get some sets of carts to work
togther.
Do you have any information about the Cardboard/3?
Thanks,
