For values of x, where x = my bank balance, 3mil * x = 7mil * x. It's all
the same to me. 8^)

I never built one from a kit but what I have been told MANY times is that
the front panel and PS were customer assembled and the front panel was an
absolute BITCH to build! Seems there was a mess of wires running from all
those front panel swiches to the motherboard and it was hell to get them
all connected correctly and to work in among all of them.

My worst run-in with a soldering iron was when I was doing some
work at my father's emergency-lighting plant *man* years ago.
They used real industrial strength soldering irons (the metal
body was about 1" diameter and the tip was a 4-sided point which
was easily about 1/4" diameter).
Well, I had placed the iron in its holder, and was reaching for
something else when I caught the cord and the iron started to
fall... my instinctual reaction was to reach out and grab for
it, which I did... grabbing it firmly with my hand... quickly
turning most of my palm and the anterior surface of all my
fingers and thumb into seared tissue...
I never did that again...

I have also had a fair # of burns in similiar manners but the one thing I
would suggest for children is to wear glasses. When I was 9 or10 I was
desoldering something when some solder splattered into the tissue in the
corner of my eye. 1/4 inch over and it could have been serious. I almost
always now make sure I am wearing glasses.

Was just going thru a stack of boards from a recent acqusition, and
discovered a NorthStar FPB-A S-100 Floating Point board.
Looks like a good addition for my Horizon system, and it even came with the
paper tape of NorthStar BASIC with FPB support. What it did not show up
with was a manual, and it is only partially assembled.
Anyone have a spare they could part with, or can carve a copy? I'd like to
try and get this thing running. Also, if anyone has a copy of the disk
based BASIC with FPB support, I'd like to nab a copy of that as well.
Thanks;

A web search turned up a reference on the Cheapass Games web site
(apparently really good games, if you like that sort of thing) to a lego
adding machine. I thought it might be the same as the one I had found
previously (that has since disappeared) but even though it isn't, it is
very interesting. Enjoy!
