Response to below:
1. The board I obtained (which is otherwise very nice)
has no power or ground tracks on it. So, I generally
solder a fat silverplated bare wire on top for +5 and
one for ground. On a board this big I put a few down
the middle also. I should have put a +5 down the
middle also.
2. The rackmount case was purchased from Jameco,
shipped knocked down, of course. It's from Taiwan,
somewhat flimsy sheet metal except the front, but I
thought it was a pretty good price compared to others
I've seen (around $42 USD). They have othe heights
also.

I just completed the very nasty job of
downloading
the
operating system and a few BASIC programs to my
"new"
PDP8, which is built from Robert Armstrong's
design...
Nice job. I've done some wire-wrap projects.
Nothing that large for,
I'm sure you can see why, obvious reasons.
One question - I noticed the large soldered "wire"
running around the
outside of the board. From the way it looks like it
goes, doesn't that
cause ground-loop problems? The books I've read on
electronic design and
layout have substantially different geometry.
Pics, if interested, are at:

Cool. BTW, your link to www.sparetimegizmos.com
has a typo in it - you
need to put an "http://" in front of it. The way
you have it, it's a
relative link to your own page.

BTW, where'd you get the rack-mount case?
