Intellivision 10 thingy

So I picked up an Intellivision 10 on clearance for $6. These have the NES in a chip in them, right? Is it possible to rewire it to run NES games, like maybe I could add a cart port or something? I counted the pins on it, but I think it lacks the connections for a 2nd player controller. Going by the NES in a chip pinouts on Kevin Horton's site, it has what I think is a 62256 SRAM connected to the Chr pins, and some strange mystery chip whose function I am not sure of yet. I would like to use it to make an NES handheld.

You're right, the Intellivision 25 and Intellivision 10 handhelds contain NOAC "ports" (and pretty nasty ones at that) of Intellivision games. I cracked open my Intellivision 10 once, and as I recall, the NOAC and ROM chips are mounted on a tiny wafer of a PCB, which is connected by a ribbon cable to the larger PCB that holds the buttons and A/V circuitry. I suspect that the design is too highly integrated to allow you to wire in a full cartridge slot; there don't seem to be enough traces going between the ROM and the NOAC.

You'd be much better off with a superjoy III, it's a nes on a chip with 76 built-in games plus a famicom cart slot all built into a N64 controller. benheck.com has details.
