Is the computer an LPX type motherboard or a full regular AT type system? Are you sure it's the video card that's not working? That should usually be indicated by the computer by some beeps (maybe 1 long 3 short). Do you get any beeps when starting the system? ISA graphics are going to limit what …

Does that mean you've not got a working floppy drive right now? It's possible to get cardsoft going in DOS manually by setting up the files in config.sys manually and running cardsoft\config.exe to allocate resources. And make sure that the PCMCIA gets some memory space left alone by himem.sys for …

The hinges should still be usable once they're loosened off, my Satellite 2800-500 has the lower mount broken off just like the one in the left of your picture, I put some thin steel with holes drilled over the hinge and screwed that together, which holds up pretty well. I'm not sure if the right …

I bought some broken VLB (very long bus) cards from my favourite recycler in the UK: IMG_1890 (2) (Custom).JPG The Cirrus Logic card was supposed to have bad RAM but it was a disappointingly easy fix, it was missing the jumpers that select which RAM bank to use. Without those it's impressive it …

I used some PTFE lubricant with the hinges mounted in a vice, working them back and forward spraying the WD-40 PTFE lubricant eventually worked out the black original grease.

In your display settings picture it says it's a standard PCI graphics adapter (VGA) meaning it's running in basic VGA mode with a generic driver. You're looking in the right place for the driver software, so it's odd it's not working. In Win98 go into System > Device Manager to see if maybe there's …

Hmm, just thought of something else, can you swap out that 40-pin cable for a fresh regular 40-pin IDE cable? (not 80-pin and not with 1-pin blocked off) Or just get some replacement regular 2.54mm 2-row 40pin & 10pin cables. There's a possibility that when the 40pin cable was separated that the …

Yep, can confirm, have been zapped a few times by the CCFL output voltage. I think it's in the hundreds of volts range. Thanks for the extra pictures, so it's a 640x480 TFT and that adapter board looks like it's running the inverter as well. If it was me then it'd be the 40-pin was for the LCD data …

What's a weak signal, like noise on the screen? What you're describing could be a backlight fault just as much as it could be an LCD signal fault - if it was a grey or white screen then the LCD side could be at fault but if the screen is just black, the first place to look is the backlight. That'll …

It's good that you know the VGA graphics is working so the graphics card itself is working right. That PCB on the side of the LCD monitor, does it go into a connector on the back of the LCD? Perhaps thats been dislodged with all the removal/reinsertion of cables. Possibly remove the PCB and clean …

Does it just not power at all right now? If it's not even powering up then it could be there's a short somewhere, or the Super IO has failed. Probably best to check the ATX connector for shorts between 5v > gnd and 12v > gnd, if it's less than 1 ohm then that'd be a short, 100ohms or 50 ohms is …

If size is really that important then one of the RISC or ARM based Single Board Computers might be better than the 1L PCs. I can recommend the HP 1L PCs though, Ive got a few now.

If you've got a way to put files onto the hard drive other than the floppy drive, test out some sound on that system - the PCM audio should use DMA just like the floppy drive uses so you'll be able to tell if the DMA is working correctly or not.
