If you want to build one of my open source projects, the PC1-XT adapter, which allows you to use some XT/ISA style expansion cards with the Commodore PC-1, you might run into problems when trying to source the specific card edge connectors that are needed. At least if you are only out to buy one or a few of each connector.
Therefore, I have now added a set of these two connectors (60 pins angled + 62 pins straight) to the store which should make things a bit easier.
