I think they're interchangeable. I know I replaced all the chips on my old Famicom with ones from a toaster NES (with a Rev G cpu). I accidentally toasted the ones on the famicom, so I had to improvise. :P

What is a "toaster cpu" ? I've never heard of this before.

Is this like replacing the 6502 in an Apple IIe with a faster one (ie, 1.79 Mhz -> 4 MHz conversion), but for the NES? I assume not, as that would seriously fubar all of the timed code paths.

"Toaster NES" is the nickname assigned to the US side-loading NES, even though the top loader looks more like a toaster.
