The first KIM-1 in my collection came with an expansion bus and a memory card. It is, unfortunately, not working at the moment.

I had one of the kim-1 my MOS. It was fun to play with and spent many hours with assembly language. I hope to one day own one again. I like to play astroids and hunt the wumpus.
