A friend gave me a LM-2 Logic monitor from Global Specialties Corp. It has a
button called the Family Threshold Select with 5 settings: RTL, DTL, TTL,
HTL, and CMOS. Did a google search trying to find a manual but no luck so
far.
Got a brand new unopened 500+ piece puzzle called MICROCHIP and it's dated
1983the cover of the box is a huge picture of a microchip circuit design.
Not sure if I should break the seal and put it together or just leave it
untouched for now?
Data General walkabout computers (3) not tested yet. Need power adapters.
I've managed to pick up a pair of "Atomic Instrument Company" Model
1091's from Purdue yesterday. They were manufactured in 1962, and the
reason that I claim that they're on-topic is because they 'count'.
Googling for "Atomic Instrument Company" brings back a grand total of
three results... nothing that looks useful. Does anyone know anything
about the company or where a schematic could be found?
These are the first things i've brought home that use a set of vacuum
tubes (thermionic valves for those on the other side of the pond) to
count.
Really neat.
I've put up a pair of blurry pictures of its front (I don't have access to
good lighting at the moment...) on my web site:
http://purdueriots.com/mr-atomic/
Warning: the pictures have a large resolution, but are only about 80kB in
size.

IBM PS/2 model 35SX - HDD of some description, 1920Kb RAM. Also with
Proprinter XL, and IBM Monitor (heavy burnin).
This is going in the skip next week, if anyone wants to rescue it from
Ellesmere Port (UK) then let me know and I'll rescue it.

Y2KFIX or Y10KFX (as appropriate)? That seems more specific.

I cannot remember what the model 100 used for a drive.
the coco and coco 2/3 both used standard (ibm
compatable) mfm, 5 1/4 in, single sided, low density
floppy drives.
the card edge connector for the coco cable between the
interface cart and floppy was a streight thru cable -
(pin 1 went to pin 1 etc).
i have used standard 360k floppys on the coco - it
only uses one side of the diskette for 180k.
if the model 100 has the same pinout and uses a
standard mfm dirve it should work.
btw the coco drive case did have a power supply in it
for the drive - power did not come from the cart.

Hello, all:
Does anyone know if the specs on the Model 100
Disk-Video Interface
is the same as the CoCo disks? I have a single-drive
DVI and a single
low-profile CoCo disk drive. They physically look to
be the same but I
wanted to be sure before I lashed them together.
Thanks.

It would be easier if you specified what these parts were - a lot of us don't
have manuals etc, so we end up looking at the numbers on the boards or other
components. Don W

For those in Europe there's a Sharp 3100 with the very
rare floppy dd on UK EPay. Has display problems but
likely not hard to fix. They are similiar to the HP 100s
handhelds and take the same memory card. Also seems
to have the proprietory laplink cable and the manual.
2Megs memory on board. Has DOS 3 in ram. I'd kill to
find one this side of the pond but overall cost would
likely be too pricey for me.
It's presently at 16 lbs with 8 days to go.

During my electrican days, we used screw heads like that to secure light
fixture covers in jail cells. They were the standard screw on jail rate
fixtures. Those fixtures used a welded frame with 1" thick lexan lenses.
