I got donated a bunch of CPUs. Along with a i386DX-20 with a soldered on pin that seems to be functional I got an i486 A80486DX-33 that is missing its S1 pin with nothing left in its place to solder a pin onto.
According to this spec sheet it is the A27 pin. I guess that means it's an address pin and is required to access RAM? I'm thinking this a critical pin, so the CPU wn't work without it, it is trash isn't it?
