Re: PCI PCB Specification

[Ivor Bowden <ivor@peritek.com>]

We don't have any problems with PCB mfg. The only problem we have
had related to connectors is 64 bit PCI cards should plug into 32
bit slots without any problems. But many 32 bit motherboards have
connectors that are too fat in the shell at the end, and the card
won't fit. Solutions have been to either modify the motherboard
connector by grinding down or otherwise cutting a slot into its
end, or to modify our PCB by grinding off pin A/B 63 (GND/RSVD).
