FYI, I'm holding forth from my "contingency PC"- which I use when my wife's on the "better" 486 in the kitchen.
I assembled this thing from old parts starting in January, and it's fought all of the way.
I began with an IBM 'opal' motherboard- 66 mHtz CPU, and 4 mb of RAM.... upgraded to 16, the max the board can hold without SIMM stackers.
The floppies were salvaged from a 386 used as a doorstop, the hard drive is a 210 mb Conner from a junk IBM, the modem's a USR 33.6k sportster. OS's have been DOS 6.22, Win 3.1, and finally Win 95, upgraded to 95a over the web.
And the keyboard sticks, the track ball is gritty, and the dang thing is slow.... but it works more or less like the other one.
and that's why there may be weird typos- it's hard to go back & correct easily!
