I have a Mountain Computer Expansion Chassis Interface card that was in a bunch of Apple II+ cards I bought. I have no use for this. As I understand it, you need the chassis expansion box to go along with it. This is ONLY the interfeace card.
I have NO idea if the card works. Physically its in very nice/clean condition. Pictures on request.
Buyer pays shipping. For shipping calculations, shipping origin is Virginia in the US.
I have not found these online for sale so I do not have a good reference for its value. Please make an offer and if it seems fair we can move forward.
