that's neat! before my house got destroyed, i had a whole section of my lab dedicated to vacuum tubes. Sadly now it's all in a box waiting for me to find a new space. My current lab just has enough room for modern scopes and stuff.
Gee, I was one of the last generation to use a slide rule. I would recognize it, but I doubt I can remember how to use it. Calculators became cheap, and killed it off.
My senior year, high school, 1971, we learned how to use a slide rule.For the younger guys, RPN is Reverse Polish Notation. It was a way of ordering operators and operands to allow calculations by early computers and calculators. It kinda reminds me of roman numerals, where IV is four and VI is six.
The SR-50 was a great calculator. It had more capability than I ever used.
Somewhere deep in the vault is a backup of our system on floppy drives, like a whole case. Coincidentally we still regularly use tape drives.Cleaning out my desk in the basement. My 30 yro kids had no clue what they are

Jumper to ground and 10* BTC make engine go brrr.Try explaining the relationship between point gap and dwell to a youngster
or the concept of total timing advance lol.
Old School Tune up
just like we did in the '70s once a year.
the # on the tach dwell is 660 rpm not 66* of dwell lol.
these 4.3s get 39* + or - 2* dwell angle (point gap .018") and 6* BTDC timing

Sun distributor machine?There is a full working SUN machine not far from my house for sale for $50. Hes dropped the price from $300. I want it badly but don’t have the garage space. My Heathkit dwell tach doe’s everything I need. But the scope would be cool

Old school is right..60+% of today’s population were not born yet…lolOld School Tune up just like we did in the '70s once a year.
That sounds about like my F150 but it’s a V8(4.6L) so 16 spark plugs instead of 12 to get 245K miles. Pulling heavy loads long distances this summer so I invested in a way to keep an eye on the transmission temp and will be changing oil a little more frequently until finished.Old school is right..60+% of today’s population were not born yet…lol
In comparison, my daily driver just rolled 250k miles on 12 spark plugs, 5k oil changes, and a fuel filter.
