I have 8086 laying about as the oldest. I have a running hall of shame processor collection ranging from 286-16mhz, 386DX 16s, 486SX 20s all the way, and just about everything inbetween, to Athlon Tbirds and Durons ( cause I will use anything after those for stuff ). I have a a few old computers that work that include a Tandy 1000 with a 25mhz AMD 386 that sold for a 16mhz 386sx on label. I also have a RARE 386SX33 which was my 2nd computer and also Doom Rig. It is a Victor so it is basically a better model of tandy... even has the 8bit DAC. Was 1993 when I got that rig and that christmas I got a 1x CD pre-MPC label upgrade that included Mantis experimental fighter, Civilization and Mediavision Proaudio Spectrum 16 w. SCSI and NEC 1x External CDRom ( still have that too). I am a sad case... I know.
