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
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?
