Out of sixth form at 16. BSEE course work done in 3 1/2. Draft number 35. Bit of trivia my left leg is my only major body part still all OEM. Repairs work just fine.

Still 100% OEM, knee just healed 100% from a mis-step off of a curb. Never been cut open for any reason, never a single broken bone, picked up a little nerve trauma in the right index finger with some careless stretching exercises without warmup.
 
Can confirm. The early MOS/LSI guys used 2 inch wafers in 1969 and 1970. Here's a two inch wafer of Mostek MK2101s; I'm pretty sure it's a 256x4 static RAM. Bob Proebsting, one of the founders of Mostek, gave me the wafer. Next to it is a US $0.25 coin for scale. The coin was minted in Y2014 and is a commemorative "Colorado Quarter".

Sorry for the lousy quality image, I just plopped the items on the top glass of my crappy Casio "All In One" laserprinter / photocopier / fax / scanner, and mashed the GO button.

Knees are really important. Lose the ability to walk well and the rest really falls apart.

Been through flood and earthquakes. No fire yet... Cut up a bit but never stabbed, shot by a hunter on posted land out of season but enough distance that shot was minor. Been hunted at least once. (No, not gone hunting.)

So Scott, do you ever do anything fun? 🙂
 
My experience is just longer than yours. You made the misassumption that the 741 came out in 1970. I had been using them for 1 year already.
Check out my contributions from 40 years ago in the Grateful Dead articles coming out daily! '-)

When we put up posts like this you little club of worshipers jump on us for daring to be rude, disagree, argue or generally not be sycophantic enough....
