Sure, yes, the old pikeaero.com website crashed hard a while back (a
power supply over-voltage failure that fried everything), and my backup
was like 6 months old, so I made a whole new pikeaero.com eComm site and
started moving all the S100 stuff (fortunately I had recent backups of
that) to 8bit.zapto.org.
Yeah I am slowly putting those boards back up as I go over each one.
Maybe I should just go ahead and put them all up as-is just to get some
input/feedback on them.
I think what Douglas and I where just talking about regarding the 4 SPI
ports (rather than 4 dedicated network ports), would supersede the old
SPI80 design I was working on. I think I like Douglas's idea of rather
than having 4 dedicated network ports running on the SPI bus, have them
be generic SPI mini-daughter-boards so you can make them be LAN ports or
whatever other SPI bus widget you want.
When I have a spare moment I'll revise that design.

Sounds good to me. Like I said, I would just like to revise it a little
to include the daughter-board concept that Douglas and I like so much.
What are other people's thoughts on the SPI daughter-board concept?
