Radius 81/100: yet another battery acid victim

Found out the battery in my Radius 81/110 leaked at some point in the last couple of years. Doesn't appear to have exploded, though I can't get to it for another year or so, in week nine of rotator cuff surgery recovery and that thing is well and truly buried.

Not too worried about the case sitting like that until I can lift the Portrait Display, but concerned more about the Quadra 950 behind it, for that I'll need to unload and handle the two stacked sections of the AppleDisplayUnit:rolleyes:

How much worse might the board get in that one year+ time period? Thankfully I snagged a spare off the 'Bay some twenty years ago, so no need to wait for an 8100 reloaded project board to modify. I could probably rework an 8100/110 board easily enough, the video connector is the only real difference I think? Only the two switches and edge of the banks of Fast Page DRAM they used in lieu of VRAM seem to have been affected. No need for schematic either, as that should be easy enough to noodle out, especially with the cherry board to buzz.

Oh well, never got around to updating the pastel phase blue paint on the bottom shelf to the brighter hues above it, so that'll be nice along with eliminating the cutouts for air return duct from it and the purple slice of the rainbow. Working with a new sheet of MDF will take less time and probably money than reviving the "new" backup board.

edit: has anyone piggybacked chips to double the available video memory on a first gen PPC.?Might work given support for additional frame buffer memory on the PDS cards?
