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.

Now here's a Funny Thing: I have a Continental Specialties LM-2 logic
monitor with exactly the same features... you have the big 14-pin DIP
clamp with the LEDs and the designator strips, as well?
Mine came from a long-ago swap meet, and most likely both our manuals
are hiding in the same place... but it's pretty intuitive how it works..
you dial up the family, attach the red and black leads to GND and +V,
attach the clamp to the DUT, and watch Das Blinkenlights. I've used
several times to repair vintage Stuff.

Thanks for the great tips I will have give it a try next week. On the dip
clamp is the name Continental Specialties but the unit itself has the name
Global on it. Serial number 224030

I'm looking for The Best of Byte, Vol II. I've got #1 already. I loaned
out II years ago and never got it back. Anyone have a copy they'd part
with?
Thanks.

Doesn't it have a rom or something on the card, ie you just do something
referencing the slot# like for a serial card etc.?
