Hi folks,
Sorry, I am not in sync with you guys. I get the digests. I try
to encourage you to think a little, and not to be too tied up to
what has been common. So a lot of my inputs are not meant to be
understood literally.

There is a few linux projects that might be of interest:

http://peloncho.fis.ucm.es/~inaky/uusbd-www/ ; USB
http://www.edu.uni-klu.ac.at/~epirker/ieee1394.html ; FireWire
( I just wrote these links, and I have not looked at them my self
yet )

selecting an address register, a strobe line, and a data latch.
Give us some info of what it can do, - do you know how many feet
of cable you can attach without problems ?
( I used 4 chips to buffer a partial decoded ISA bus, which run at
the ISA bus speed, but I have not tested it for cable lengths and
noise. The output is a 20pin Header type. But I may have an easier
idea )
