BPPC is expensive and will remain so. I'd also expect that DCE would want lots of money for the licence if they hold it.
Returning to the Apollo 630 I hope the PCB is redesigned as it was notorious for faults such as popping off the 68k socket (needs some clips) and not having any heatsink (bad move). Also I'd rather they ditched the 68882 socket totally and made it smaller instead. The Viper 630 with onboard ram was a tidier design and as long as this had 32Mb of Ram I'd be happier with onboard ram.
BUT
If Individual Computers can build this sort of kit then why not build more interesting kit.
Mick Tinker still has the designs for the Inside Out (Amiga on a PCI card) - just needs s/w developed.
What about getting the Boxer PCI design from AntiGravity?
