I got all these from a recycler, all from Capcom in Sunnyvale. Some pinball etc, game cards, I have more pics if you want to see them email me . Taking best offers
The first board is the first version of the Playstation 1 dev hardware. There's supposed to be a second card to handle the CD-ROM. The second boards contain the CPU used in the 32x if I'm not mistaken. I'm curious as to why they're on separate boards. The third is an empty prototyping cart. EEPROMs would be installed in it to test in a real Genesis.
I'm interested in Sega gear if you've got any more.
