Are you serious ? S-100 went out with the ark.
The S-100 bus, IEEE696-1983 (withdrawn), was an early computer bus
designed in 1974http://en.wikipedia.org/wiki/S-100_bus

I got a chance to start skimming through the pages, just now. Some
initial comments.
(1) I really enjoyed the breadth of example pictures included. That
really helps a lot.
Hi Jon! Thanks!
Yes, I've added some pictures and many of the N8VEM home brew
computing builders have added theirs as well. You can see all the
N8VEM home brew computing project information at the wiki and the
mailing list
http://n8vem-sbc.pbworks.com/
http://groups.google.com/group/n8vem
Any and all interested in home brew computing are welcome to join and
discuss. PCBs are available for all the projects; the N8VEM SBC, ECB
backplane, ECB bus monitor, ECB prototyping board, Disk IO, and Zilog
Peripherals boards. Some of the N8VEM builders have their own project
PCBs available too like James (miniN8VEM and derivatives), Vince
(PockeTerm, etc) and a lot of other stuff. Its too much to describe
so you're better off just seeing for yourself.
My original post was regarding the S-100 backplane I am developing and
looking for experienced S-100 persons interested in joining that
aspect of the N8VEM project. I'd like to branch into S-100 related
stuff and am exploring the options at the moment. The other N8VEM
projects tend to be ECB Eurocard style neo vintage computing items.
However, there are some PICAxe, Propeller, and various other things
underway at any given time too.
(2) I normally disallow pretty much all permissions on new web pages.
What first showed up was a nearly blank page, as a result, without an
indication that permissions should be enabled. (I knew it, of course,
but it always helps to set things up so that if the web page may look
confusing that a helpful message appears to suggest a direction.)
Yes, pbworks is rather complicated for my tastes but it works and is
free so its OK. I'd prefer something a bit simpler myself. Like an
FTP directory.
(3) Once enabled, the preview of JPGs that appear when the mouse is
placed over a link is much appreciated! That is something that I now
know I wish happened more often on other pages. Keep that up!
Other than that, I'm still reading along and thanks.
Well if you or anyone else are interested you are welcome to join.
You don't have to purchase PCBs although it will be fun to put them
together and discuss your favorite topics with the other builders.
Its not a blog or business but just a bunch of friends who like home
brew computers.

Some people debate whether something you build from a purchased PCB is
really a home brew computer and I can see their point. However, all
the N8VEM PCBs I have *did* start out as a home brew projects.
Typically they start life as a blank piece of paper and a DATAK
prototype board although lately I've been using these N8VEM prototype
boards.
The N8VEM ECB prototype boards make it so easy I feel like its
cheating. That is especially ironic since I originally did not
support the idea of a prototype board but so many builders asked for
them I felt I had to. Now I am the biggest consumer of them - oops.
All the builders get is the PCBs and they do the rest on their own. I
supply schematics and PCB layouts. Occasionally a preprogrammed EPROM
or hard to get part but for the most part its "sink or swim" for the
builders. An amazing percentage of them get them working too. Its
close to 100% or at least I don't know of anyone that *hasn't* gotten
them to work. I suppose there are some who never finish their
projects but I don't know of any. The builders share a lot of
information from their builds so new builders do get quite a leg up
now. The first batch was pretty sporty though.
Thanks and have a nice day!
