Would a Super Famicom board fit in a SNES shell?
I'm pretty sure the motherboards are the same between the two (though there are several versions of the board)... though yeah, the power connector is different, and maybe RF as well (never tried).

The last time I was in the market, you were looking at about $30-40 (shipped) either way. With outliers trying to get $50 out of you (local game shops, easy to haggle back down to $40.)
SNES systems seem to have gone up quite a bit lately... I was trying to buy some to harvest CPUs from, but they were just too expensive. I ended up buying 10 working SFCs from Japan instead (along with quite a few broken SNES motherboards, with mixed results).
I bought from this seller (shipping is literally the "slow boat"... takes ~2 months by boat from the Port of Kawasaki):

I have an old SNES that behaves oddly. The Mode 7 map in F-Zero is corrupted, so that you're driving on random terrain instead of track, and of course you rapidly run out of power and blow up. Super Mario Kart has no such issue, but the Mode 7 graphics at the victory podium (the fish and the congratulations) don't appear. Super Metroid doesn't display the map properly, and there are crucial powerups simply missing, making the game unwinnable. Yoshi's Island displays garbage background graphics, but is otherwise playable. Gradius III seems to work fine. My Super Everdrive doesn't work at all; it just displays an error message.
If you're able to, I'd recommend running the Burn-in cartridge to see what the self-test says. It does sound like a CPU problem IMO though.

Hmm, DogP has a pretty good sample of broken chips, so first thing might be to decipher the date codes and see when they were made. Does anyone know what the numbers and letters mean below the 5a22 text?
My sampling may be a bit biased, since a good chunk of those chips came from Nintendo Super System motherboards, which was probably fairly low production and short time span (especially compared to the SNES). I think every Super System motherboard I've come across had a Rev A CPU. A lot of the SNES motherboards also had Rev A, though quite a few also had the original (no marking). I've only had a few Rev B... though I haven't seen a bad Rev B yet. If you look at the pic of the 24 CPUs, 21 are Rev A.
I also wonder if the abundance of Super System failures are caused by arcade life, more than just age. For example, the SNES/SFC have a 7805 regulator to give clean regulated voltage to the board. The Super System runs directly off the +5V from an arcade switching power supply, which is on the other end of 5 feet of wire and several connectors, is user adjustable, drifts over time, etc. So, rather than a nice +5V regulated on the board, it could be getting 4.5V or 6.5V (nobody thinks to check/adjust the voltage unless it isn't working). And in the arcade, they were left on for 12+ hours every day. I know one guy that sent me his motherboard said his voltage was adjusted to 6.5V... his ended up only having a bad PPU1 (games played fine, but graphics were all blocky and had wrong colors).
