Lets use this issue to track problems with PCB design v0.2
Provide a way to terminate the _FPUCS by generating _BERR when FPU is absent.
Some local bus slot pins are incorrectly numbered (rows 2/3 and 6/7).
Provide a way to block _AS/_DS delivery to main board, in case we are decoding the address on a card (not really a problem now, as we just use _RAMSLOT, but in the future we might want to decode it in CPLD).
Connect _CIIN to CPLD, without that we can't control cache inhibit and possibly violate timings.
Pins 119 and 120 of QFP are mismatched.
The PCB has wrong dimensions that potentially conflicts with A3000. The board size should be based on CyberStorm Mk-III/PPC, which is known to be compatible with all existing Amiga models featuring local bus slot.
