I've seen a couple of implementations of that idea, the local one round here
was the "County Computer" The model name and designer of which escapes me
right now - this is a while ago - Very nice machine though, very solid
compared with a lot that were around back then!
We really didn't get to see a lot of the people involved in the designs of a
lot of this here in the UK at the level I was working at back then, most of
the time we were just the guys that went and fixed them when something blew
up!

I always found S100 things interesting, there were quite a few we supported
over the years, Cromenco, Comart, Equinox, Northstar, Jarrogate and the
like - they all had their good and bad points, well mainly bad in the case
of the Jarrogate Sprite, unless you have a need for toasted 74LS245s!

I'm just starting on PHP and MySQL that's well more than enough right now
for me, it's been quite a while since I sat and wrote a real program!

Hehe, thought as much - if I get bored later I'll pull a databook for 4116
Rams and work out the static current draw for that much - could be quite a
surprise!
