Ladies and gentlemen,

She's in.

Tomorrow (or even today, if I make it), I'll take the console apart and test the continuity (and detect potential shorts) between the pins to make sure it's making full contact. I've hooked up the power lines, chip select, read enable, the first 8 bits of the data bus and the first 18 bits of the address bus (up to 256 kB ROM possible, which is more than enough for me), which should be enough to get a ROM to successfully boot.
