unscrew the fan from the heatsink to get a little bit more space for leverage, and use a flat head screw driver. Be careful not to slip !!! or push down too hard and scrape the board.

probably. as long as the max current stays under 1A... though What are the voltages on the regulator pins now ? Should be one pin with the incoming voltage on, or slightly less one pin should have nothing and one pin should have 5v.

Depending on the interface of the USB floppy drive, you could directly exchange it with any other normal floppy drive, or it might need a small adapter board, or if you have a laptop floppy drive you could use that. YMMV. good luck.

those are for the horizontal & vertical deflection. I'm guessing if you need to swap the wires or not will depend on the correct screen output. display would be mirrored, either left-right, up-down, or both.

Maybe it's running at 16MHz despite that the BIOS sets it at 12. Considering the setup program you are using was for a …
