Yes, my first manual computer was an abacus ,
People were able to do amazing things with primitive computers back then. The Apollos, ICBMs, and even the Space Shuttle flew with these. The limited memory capacity and speed mandated some clever programming.
Young programmers tend to turn out bloatware. They should be able to practice LBYM in programming as they have so much at their disposal, but instead they squander all these bits and bytes and CPU cycles.
One of my first programming assignments in college was to write a program using PDP-8 assembly language, convert by hand to machine language, then input the program using the switches on the front of the machine. If I recall correctly, there was a set of switches for the memory address, and another set for the data. Set both of these then hit yet another switch to store the data at that address. One of my best learning experiences ever.
My first computer of my own was an Osborne 1 in 81-82, I only knew a handful of other people who had their own computers back then.
I remember BASIC, and dropping a stack of punched cards that I had failed to number. Everyone did the card drop - once. Those punched cards made nice Christmas wreaths, remember?
We used to have a saying. Twenty year old computers went to the Boston Computer Museum. Twenty year old batch programs went into production every night.

I still have my K&E slide rule but don't now if I remember how to use it. I don't think I will bother trying to use it again.
Still have my log log slide rule and still remember how to use most of the scales. Also have my grandfathers 20 inch slide rule (not log log however)I still have my K&E slide rule but don't now if I remember how to use it. I don't think I will bother trying to use it again.
This talk of punched card wreaths got me thinking...
You know, punched cards are easily readable. Heck, a lot of the key punch machines would print at the top too, for human consumption. And I knew people who could READ punch cards with their eyes like someone would decode braille. I even learned to easily read the numbers 0-9.
Can you say "Identity Theft?" I know, I know. It was different in the 60's and 70's. SS # were widely distributed. But still, I could see easy abuse from a stack of payroll punch cards -- if nothing more than for the rumor factor. Imagine going to a friends Christmas party and while there, you could read everyone's weekly salary as you stare at the folds on the wreathe.
I guess we were all just more innocent back then.
