[Hardware] Fully unrolled RC5 on FPGA

[John L. Bass]

Simple comes in a lot of flavors ... PCI target mode is pretty simple
interface, barely more complex that direct ISA attach.

While this particulare project requires zippo bandwidth, others might require
a bit more than a simple USB target device at 400kbps.

PC cards provide power and mounting ... past that requires extern
power supplies capable of probably better than 20W.

That said ... adding a USB single chip solution isn't a layout burden.
And having a few fingers on the card isn't a problem for mounting it
in an external case.
