Pardon me for what is essentially a re-send of a previous query. I
noticed that after I transmitted the below msg, that I experienced a
period of over 18 hours with no mail received from the rtl list nor from
any off-island source. This is unheard of since I subscribed to the rtl
list :) Thus fearing that I may have missed any replies I am re-sending
this query. If there is a more appropriate forum in which to pose this
query then please let me know. Thanks.

We are embarking upon a port of several existing capabilities hosted on
legacy H/W and OSes to an Intel Pentium PCI-bus based realtime Linux
platform. So the search for I/Fs with some level of existing (realtime)
Linux support begins. We will need:
4 RS-232 I/Fs
8 16-bit parrallel (most used uni-directionally)
2 8-bit parrallel (obviously could be wider)
2 10/100 Mbps ethernet
1 Irig-B time code compatible synchronized generator
We are free to select whatever motherboard and I/Fs required. Only some
of the serial I/Fs and 16-bit parrallel I/Fs need realtime response.
One thought has been to have duplicate boards of the serial and
parrallel I/F types, one controlled by standard Linux and one controlled
by realtime S/W. Our application is more noteworthy for the number of
devices to which it interfaces, and not the I/O nor number crunching
throughput.
Are there any thoughts about preferred equipment choices for the above?
Of course, we would like existing (realtime) Linux support as much as
possible :)
