I am working on a project that requires many discrete transistors. Suffice it to say, it is for a transistorized 4-bit CPU project. I came across some oldschool IBM info on Wiki, and would like to do something similar to this:
IBM SMS Cards (scroll through to see application)
I want to follow the traditional approach of having all the logic gates on these cards and have them connect to a wire wrap backplane. I've had a heck of a time finding not only Eagle libraries that support a card edge connector, but it seems impossible to find the exact connector to go with it. Even something as mainstream as PCI has a million variations.
The cards themselves will be 3x4" single sided copper boards that I will etch myself. Ideally, the card edge would connect directly to a DIP wirewrap socket. I'm really not sure the best way to go about this. I would like an affordable way to connect these 3x4 cards to wirewrap, and would prefer to be able to make the PCBs for the cards vs. using proto/vero board.
I've thought about using angled pin headers, but the card edge seems cleaner and saves a lot of soldering.
I know wirewrapping is antiquated and I also know that having multiple logic cards is as well. But, this is a hobby and I would like to use old technology.
