If the 68030 bridge side of the PBX can handle a transfer every cycle I'll eat my hat. Burst mode on the '030 is a word every other cycle and that's usually only applicable to RAM, so realistically the upstream bandwidth of the PCMCIA controller is probably closer to eight MB/s, not 32. (Coincedentally,that's about what ISA is capable of.)
