It's been a while since I powered it up, but I've got a COSMAC Elf somewhere. 
CDP1802 CPU, CDP1864 "Pixie" graphics chip, 256 bytes of RAM, and a core clock 
of 1.789773MHz (3.579545MHz divided by 2). The whole board is running on 5V, 
and works fine.

I don't think I ever did anything remotely interesting with it, but it's still 
a neat toy.
