Last year I grabbed one of Lee Hart's "VIP2K" modern re-imaginings of the original Cosmac VIP.  It's not exactly the same; it has an OS with a bit more functionality, and the Chip8 interpreter isn't the original one, but a recreation based on it by Marcel van Tongeren. But it uses a real 1802 microprocessor!

Getting involved in this Jam has given me a chance to fiddle around with it some more. Here is a short video of it running the OctoJam 7 promo program.
