A couple of neat cards I picked up recently

These cards were part of a piecemeal clone system called the "Appleseed" produced by Douglas Electronics. It was designed as a turnkey system where you could buy only the components that you needed to build a product. There was a small bus board and then all the pieces of the Apple II were available as cards - a CPU system card, a memory system card, a video system card, ROM, IO, etc.

These are the CPU and memory cards. Although I don't have any other components (there are a couple others evailable on eBay), these are the most interesting for working with a full Apple II/II+ as they replace the CPU and memory when installed in an Apple II. So, problems with those systems can be isolated quickly. Anyway, a couple more unique toys for the collection.
