There are, or at least WERE, 8 bit ISA PCMCIA adapters.
Recall any? I'm really looking for something like this.
The speed of the CPU is irrelevant for my project; what I *do* need is a way to
pump 200KB/s through the machine, and the WD 20MB MFM + controller is only
giving me about 80KB-100KB. (interleave 3:1, adjusting it in either direction
reduces throughput)
What *is* the bus speed of a 4.77MHz 8088-based PC anyway? ie. what is the
theoretical maximum amount of data per second that can go through the bus?

There are ISA adapters for PCMCIA. There are adapters
to plug CF into
PCMCIA dlots.
8-bit ISA adapters? To clarify: I
want to add "solid state" storage to a 1982
IBM PC rev B. machine (to see if I can get any faster I/O than the MFM drive
hooked up here)
That would certainly reduce the I/O bottleneck,
but 4.77 MHz will never be "fast".
