A while back, I got a Sanyo MBC550 motherboard, and I want to restore it at some point. The problem is that someone removed the keyboard and composite video connectors. Whoever did it desoldered the composite video connector, but was terribly lazy with the keyboard connector and simply cut it off the board.
Since the motherboard is two-layered, it's easy to follow the lines. But I haven't found a suitable photo of the underside.
I sent images (and some references to software, info and the bios) of mine to theretroweb (I edited the cut part in the image from above, cloning the other connector) for a new entry.

So, I would appreciate it if anyone has a full picture of the underside with enough detail , or has this PC and could take a detailed photo of that part of the board.
I have the schematics, and I can see the keyboard and controller connections, but an image would help me do the job even faster later.
Also, to make a better, more complete picture for the retroweb

Pondering whether to try some retrobriting. Picked up a "Sharper image sanitiser" which appears to be a UV-C unit with a 4W tube. Has perforated metal around it though, so not sure if it will do a mottled pattern. Has a 10 minute timer, not sure if that would be enough to zap an EEPROM or whether it would take 2 goes.

Haha! In a few days, I'll try a toothbrush sanitizer. So far, I've erased all my Eproms with a couple of weeks of sun exposure (shiny tropical sun, fast retrobrite is a bonus 😀 ). Since I have several of each type, I can do a few tests before needing to take a couple of weeks to erase some. Believe it or not, it's a bit difficult to get a dedicated eraser where I live, although it would be a bit easier for me now. I was also going to build one with UV LEDs, but now I can get this for free, if it works.

Yeah I've got another UV device, a cellphone sanitiser that just seems a bit difficult... can't get an EEPROM to sit sideways in it to get close to emitter... just for phones slimmer than 10mm I guess. Has annoying lid interlock and smash to access construction, so didn't feel like re-engineering the whole damn thing yet.

Marathon fixed the 4 working mobos from this month's first lot:

- ABIT ST6-RAID - recap, one socket tab unfortunately broke off so might need constant supervision when using 462 coolers
- Gigabyte GA-6BXC rev2 - cleanup, BIOS IC, 2032 holder
- Soyo 6BA +III - recap
- DFI P2XBL Rev D - cleanup
