I think both me and @Kai Robinson have considered the IIsi and IIci but they are 6 layer boards so require completely redrawing like @Bolle did with the SE/30 rather than just tracing. I'll defiantly be looking at them in the future though if someone doesn't beat me to it
Methinks
@Bolle is already well on his way down the IIsi road. Just before I started bugging you about morphing your LCIII into the Compact form factor I was posting about reformatting IIsi for the SE/30, driving its CRT from Vampire Video at 12" RGB res. ISTR he PM'd me saying something like "it catched me somehow," had mooshed some components around into the outline of his SE/30 design and included a partial rat's nest pic.
That'll be killer if and when. 20MHz board with PowerCache, NIC, NuBus Slot AND his GS card in a Crystal Clear Case should onboard Vampire crap not prove sustainable.
PowerSE/30si upgrade supported too!
