design question...

[Gregory A. Parmer]

I keep listening in to learn others approaches, but I'm always
looking for a better way. Does anyone have the specs/response 
time of the SCSI bus handy?

It seems to me that a "black box" for I/O would be the best solution
*if* the necessary bandwidth/response time could be achieved using a 
parallel, SCSI, or maybe a PCMCIA bus.  I'd just like to see some 
room for greater flexibility in design than a dedicated controller 
with a mondo i/o bus (although I realize that the "black box" design 
could be a timing nightmare).  An industry standard bus would be a
major advantage if it could be done.

==============================
|  Controller                |   (parallel, scsi, or other standard)
|  (anything from a SBC to   |<--------------------------
|   a notebook PC)           |                           |
==============================                           |
                                                         V
                                          ===========================
                                          |    I/O "Black Box"      |
                                          ===========================
                                            | | | | | | | | | | | |
                                            (Multiple ttl i/o ports)

Are the neccessary response times not possible?
