8550 Riser Hack

From David L. Beem:
   I trimmed the clear plastic (darker center area of the riser) around my solder pads & scraped the insulator coating away with a knife. Tinned up the leads & solder pads liberally to put them in place.

The red 5 volt conductor should be positioned to the side of the solder pad as I have it because a plastic rib on the drive platform will interfere if it is centered. The finished hack looks like this:

Ed. Maybe a shot of hot melt glue to help keep the conductors from being pulled around and fatiguing the solder joint?

Warnings and recommendations from Peter Wendt:
   Remember, the Model 50 power-supply (94W!!!) is known to have lesser power than assumed. If you'd already installed a 386/486 upgrade, 64Megs of RAM, SCSI adapter and a hi-resolution graphic board it will surely collapse.
