When I remember back to the early 80s, me a single digit aged human with my first Commodore 64 and a cassette tape drive, to being a high school aged kid and helping my buddies install their extended memory set chip by chip to get them to 1mb of ram, to way in the future where I type this comment on a mobile phone touch screen capable of unfathomable high resolution graphics and speed is still a surreal feeling.

I grew up and grew old with computers and it’s wild to imagine a life without and a world without them nearly 50 years later.

A computer with a spreadsheet was a HUGE game changer.

In '85 most companies did books by hand and adding machine. Records were kept in ledgers and in filing cabinets. People used to hire CPA's to come in and do the balancing even in small convenience stores. Given labor wasn't what it is now, but a machine like that could pay for itself pretty quickly.

I worked a fast food job in the 90's They had an ancient box running 1-2-3. Every night, the MOD would have to sit down with a paper sheet and an adding machine to generate this table, then enter all the transformed data into Lotus. They literally sat back there for hours working over the data. I asked, why don't you just change the sheet to do all the calculations? Can't, the franchise owner wants it all done by hand. They were literally taking a row of numbers, doing some math on it, then doing more math on each column to come up with a final row of like 7 numbers.

I had them show me what they were doing and wrote a program on my TI calculator to generate the table from the input numbers. Told them if they wanted the program just to get the same calculator and I'd transfer it over.

The old computers from my childhood still boots faster than any modern OS 😎
