In the past two years I rebuild, from parts I sourced in various places, a fully working; 286/16, 386SX/20, 386DX/40, 486DX/100. I also have the parts for a Pentium 100 except for the CPU.
It was fun collecting and sourcing the parts and building the machines up. In my opinion the PC industry in the 90's was most interesting, not because it was "my" time but because technology was advancing leaps and bounds during that period.
