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.
