I'm still convinced that a harvested NuChip Bridge ChipSet transplanted to a new PCB layout is the only way to go . . .

1) near certain compatibility with SE/30 do to architectural considerations

2) no extra FPU to get in the way/muddy the waters

3) placement of TWO NuBus slots in the space of the relocated HDD's cubic is possible

4) reverse engineering the SE/30/IIsi PDS <-> IIci cache adapter slot for a new PAL layout seems eminently feasible for PowerCache jockeys

5) Using an Asante Nic with with the removable Thicknet passthru card allows for breakout of a HOT 7"+ NuBus VidCard's DA-19 lead or doing an internal cable conversion to HD-15 VGA sticking out the modified backplane I/0 panel

6) a 10/100 Nic might be feasible in the second slot, freeing the third address for a card installed in a straight PDS passthru somewhere else on the card

. . . and best of all, the adapter can be made to fit the inside of the SE/30 like a glove! :approve:

edit: bbraun told me he ripped the CoPro off a NuBus adapter, but needs to see if the traces damaged in the process are a doable fix.
