or the 286 for that matter.. i plugged up the psu and powered on... wow it booted.. quick get the phone to take a pick of the boot screen as there is nothing on the board to ID the maker.. i mean nothing.. and i'm not the only one with one of these.. then come back in kitchen to a plumb of smoke.. shit... turn it off.. took out the psu and an electrolytic cap went.. and i don't have any 22uf at 250v.. so it will wait for them to come in.. i did see it's a T.M.C in bios but all i have seen are not mine.. the CPU and ram are in the wrong places. i have worked out the speaker connector.

plugged it all together and power it on all good no smoke get a bios beep because i don't have keyboard plugged in.. so check screen and nothing.. power down and re-seated the card and check plugs.. and test again.. still nothing on screen. tested the 3 voltages going to the card and all are in spec.. so i will have to do some head scratching.. i even tried the other video card and still nothing.
