No, I never made Quake levels. Mine was an SX-20 and it played ok, but building a level complained about a math co-processor. I tried an emulator once, let it build all night and it still wasn't done.

Salvation came through Wal-Mart of all places and I convinced my mom that this $20(or $40, maybe I was paying half?) chip would just drop in that empty socket and double the speed of our computer. 486DX-40, that was nice...
