LMAO, I have a handful of i80386DX, 386SX/387s, even a few 286's +
mainboards and a crap load of 30pin and 72pin SIMMs if someone want to
"upgrade", if you can't find an old Pentium I / 486DX4 systems in the
garbage there's something wrong with you.
But seriously... There's still very good uses for these old timers in
embedded control systems, routers and such... I WISH the mainboard
manufacturers would make new mini-ITX, FlexATX, and MicroATX format
mainboards and chipsets for these old guys, yes really!!!
