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

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?
