The 486 SLC2 is an oddball 486 chip made by IBM. It isn’t something anyone seems to talk about much, maybe because I’m the only one who finds its story ironic. It’s the story of a proprietary upgrade that found second life on clone motherboards. Except the clone motherboards were made by IBM themselves. If IBM made it, is it still a clone?
