Saved an old IBM from the trash pile and opened it up. It is about 9 years old. It is an old TX486DLC/E 40 GA on the chip on the board. It has an empty overdrive socket. Had some old memory chips so I upped memory to a gargantuan 40 mb. Has Win3.1 on it. It still runs and boots right up into Win3.1. My question is if I go to expense of putting a cdrom in it (about $30) will it run Win95 or Win98? I wonder if I could still find an overdrive chip for it and how much would that speed it up?
