An impossibly rare vintage 1979 Connecticut MicroComputer CBM PET Xpandr1 Interface.

This is essentially some kind of port multiplexer for the CBM PET range of computers.

A copy of the instruction sheet will be included.  It looks pretty, yet I've no idea what to do with them other than put one in a frame.

No other accessories are included.  Any excess postage will be refunded.

All items are USED and will show signs of USE.  All items are photographed inside and out.  All items are SECURITY MARKED and have a non-removable barcoded security sticker to prevent tampering.  It will not be possible to remove or replace internal components without destroying the security measures.
   

All international orders must be shipped using the Global Shipping Program (GSP) and cannot be sent by any other means, including directly to an address.  The GSP protects both the buyer and the seller against postal issues and loss or damage in transit, and also ensures there are no problems with import duty or taxes.
