Programmed Chips for XEP80II
This are the two programmable chips for the XEP80II (Char ROM and OS ROM). They have been pre-programmed for your use. Just put them in their socket and you are ready to go. This is for two 28C64 (or equivalent) chips, pre-programmed. They are for locations U3 and U11.
This is a DIY product. We will guarantee that they are working and correctly labelled and programmed, but since you are putting them in a DIY product, there are non-refundable/non-returnable.
This is a total for BOTH chips. This is all you need for the project.
