One of best 486 PCI motherboard. Photo is of the last sold item but I have them in identical configuration/state (except potentially cpu swaps)
Dallas desoldered and put socket.
Soldered hidden jumpers for setting all needed configurations.
Bios upgraded.
Double banked cache for best performance.
With this mobo you can play with AM586 @200 (at least for a while during boot).
I have selected cpus which runs at @180Mhz and are potentially good for @200.
Final config & price can be specified.
In standard set I provide: mobo / cpu am586 / initial ram.
