Hey there,
I have been putting together my new retro machine, but unfortunately I can't quite get over the first step. For the sake of troubleshooting I disconencted all non-relevant devices.
Which leaves:
-A Super Socket 7 Mobo, exact model unknown, but it's extremely similar to M598, attached the manual
(-That Board comes with an Onboard graphics card, meaning an output goes from the mobo to the side of the case)
-K6 350Mhz
-AT Power Supply
-AT Case
-2 X 128 Mb RAM
-AT Keyboard PS2 Mouse
Everything else is unplugged (I left the IDE connectors attached on Board, but nothing is plugged in)
The Board+CPU+RAM have been tested before with the system they came with, and they worked. I did not change any jumper settings or whatnot. However I did remove CPU and RAM and put them back into the same slots.
-The AT Powerplug is (to my knowledge) plugged in correctly, having the 4 Black cables in the center.
When I press the power button, the CPU fan starts spinning, the MHz LED Lights up, the power LED lights up, the yeyboard LEDs light up briefly, but the VGA Monitor does not get a signal, just nothing happens. (meaning I also dont get into BIOS)
I have pretty much no idea what could be wrong here.
Maybe the Case Connectors are connected incorrectly (See Manual). I only plugged in the PC Speaker(1,3,5,7) and the Reset Switch (17,18). There are pins for the power button, but I guess they are only needed if you connect with ATX cases. From the manual it sounds you can put the PC into "suspend mode" with that. Power LED should not be necessary as its taking the signal from the Power Supply (and it lights up).
Also I thought maybe I damaged the ram or its not sitting in correctly. I removed it, same result without any ram installed, and put them back in.
Hopefully you have any idea for additional troubleshooting steps.
