I recently won an auction described as a "Science Fair Junior
Electronic Lab 10 in 1"... the picture showed a couple of
blue grid boards which were, AFAIK, not part of a 10-in-1
It turns out that in addition to the 10-in-1, there was
an entire (and a partial) "Science Fair Junior Project
Board Kit" (cat no. 28-153) - one manual, two plug boards,
one IC board (14-pin socket + 14 springs) plus a double
handful of mixed loose components.
The components are somewhat interesting from a historical
perspective - there are several flavors of transistor sockets,
several segmented LED displays (some on PCBs as from an LED
calculator, some in DIP form), mercury switches, reed switches,
and a bag of resistors with a "King Kits" card from Poly Paks.
I'm curious if there's a repository of ancient Radio Shack kit
manuals out there - I did not get a manual for the 10-in-1
(cat no. 28-225), but at least I got its box (covered in packing
tape, grrr.)

Would a scan be adequate? I have a 28-225 and could (in time) send you images. Of
course, if you are collecting, that won't help.

New subject: How to build a working digital computer book
I recently acquired the awesome book "How to build a working digital
computer" by Alcosser, Phillips and Wolk. Within the next year (as time
allows) I want to (re)construct this computer.
I know this book was discussed on here before. Maybe there are other people
out there now who are in the process of building it or built it before. I
would like to get in touch with anybody who has experience building it.
The only website I found on so far that shows a built "Paperclip computer"
is this one:
http://www.apparent-wind.com/mbr/emmerack.html
If anybody knows any other pictures of a built "Paperclip computer" on the
net, please let me know.

Hi Bryan,
well, that's no secret, I found it on ebay... :) It was "buried" somewhere
in the "wrong" category.

Simply incredible! What a terrific site. I wish there was more
information though.

I have an original brochure for one of those. Any idea how much
the actual computer would go for these days? Has anyone here _seen_
a real one?

No, but the one pictured is from the manual of an actual unit that Doug
Salot bought from a company that went out of business a few years ago and
was still selling them up to that point as educational tools for teaching
computer principles.
I assume Doug still has it.

New subject: NeXT monitor problems.
Hello,
My NeXT mono monitor (N4000A) quit displaying properly. Symptoms were:
1) Over last 6 mo. or so, on start-up (this is only about 2
start-ups, machine running continuously in between), the middle 30%
or so of the display was compressed into a single (bright) scan line.
Top and bottom 30% were stretched, so the whole screen was
continuous. This problem cleared after running for 1-2 minutes.
2) 4 weeks ago, noticed that (even after the start-up problem) what
should have been a uniform grey background looked like it had small
light and dark horizontal flecks in it, appearing and disappearing at
something like the screen refresh rate. Made the background look
grainy and sort of seething.
3) (After I was gone for 3 weeks on travel), monitor now flashes on
and off on about a 1 Hz cycle time. A distorted and shrunk version of
what should be showing is visible near the center of the monitor
during the "on" times. There is a bright horizontal scan line near
the middle of the image, when you can see it.
4) On start-up, nothing shows for at least 2 minutes. After around 2
minutes (as I was powering off), image (as in 3) above) started to
appear. Have not repeated experiment to see whether it goes back to
the 1-Hz cycle or not.
Monitor has been running near continuously since I got it, in '96.
Is this a known/easily fixable failure mode? Anyone have
experience with this? I need the machine running and my record with
repairing computers is dismal so I'm looking for (and think I have
located) another monitor, but at some point I intend to take a crack
at fixing this one.
Replies to list if you please, in case this *is* a common
problem - I'll catch up as fast as I can.

That would be fine. Don't send the scans to the list (they'll be
filtered out, anyway). Put them up on a website and make an announcement.
