I got hold of the schematics online (there's only one place that has it but can't remember the name) but after comparing it to the board i had they didn't match up?
Basically i want to make a SMS2 card slot. I would have thought it would have been wired in the same as it was on the SMS1, but it seems the boards are different?
So, are there any more hidden corners of the www where i can find more schematics?

Yep, that's the one. The pin-outs on the IC's on my board do not match with those on that schematic?

Hmmm, I seem to remember I saw another somewhere. Let me check around some.

I have this thing I found on here that I had for reference. Is this what you're looking for? Not sure what they have on there, but perhaps it's for the Mark III.
