I had the Commodore 1541 calibration kit and used it many times. Click, click, click ...
At a temp assignment one college summer where my job was basically just supporting the lead accountant, doing things like sorting RMA slips, I ingratiated myself with the greybeard who ran the IBM mainframe (System/370 maybe?), and he let me do some mindless data entry. Some of it was truly mindless, like sequential numbers or something, so when he wasn't looking I dug into the binders (a whole wall of them), found the registers that the DB was using, and automated it. As is typical with most such efforts, automating it absolutely took WAY more time than if I had just mindlessly typed it in, and absolutely ran the risk of corrupting the entire database. But where's the fun in that?At another such job I worked in the tape library adjacent to the mainframe room. The greatest thrill was when they let me in on the console to type in the commands that reprioritized up some VIP's batch job.
I spent a ridiculous amount of money on a 12 MHz "zero wait state" PC/AT clone.
At the time, teenaged me already knew that computers would take over ALL technical fields, and thus I did NOT want to major in Comp Sci, rather some other engineering sector, since I knew I'd work with them plenty.
Space nerd since a kid. I watched the Lunar landing live, and rode my bike to a newsstand where I bought the LA Times on July 20, 1969 for 25 cents. I still have that yellowed newspaper.My mother worked for TRW in Redondo Beach, part of the group that built the Lunar Module Descent Engine. After the successful end of Apollo 13, the astronauts visited TRW to speak. My mother let me skip high school that day and I shook hands with all 3 of the Apollo 13 astronauts.
I built my first home computer from a kit in 1977 when I was 27 years old. IMSAI 8080. "Built from a kit" meant soldering all of the components onto the PCBs and point-to-point wiring of the big unregulated 5v power supply (transformer, huge electrolytic capacitors, power diodes...)Kit cost about $1000 in 1977 dollars. 8-bit processor with 2Mhz clock, 4 Kilobytes of memory, audiotape storage, no peripherals until I added them later. 22-slot S-100 backplane (that's 2200 individual solder joints). I eventually added a salvaged CRT terminal, a used daisywheel printer, and dual 8" floppies, 64 kilobyte memory, and later a 15 megabyte 5.25" hard disk. Ended up writing the business plan for my first company on that machine.
I fell in love with computers with my very first college level course (a one-credit introduction to FORTRAN and punch-cards), and wound up buying time on the university system the next term in order to play around. Later that year (1977), I got a job at Radio Shack, and was there when they announced the TRS-80. I wound up being my store's fourth customer for one. I must have spent half what I earned at that store on things they sold. I had to sneak the computer into the house since I knew my parents would not approve of me spending so much money on what they would think of as a toy. They were quite "frugal", having grown up during the Great Depression and WW2.In any case, I was the only guy in my school of engineering with a PC of any sort, and took full advantage of the fact. Even if it was only an 8-bit Z-80 running at less than 2MHz with 48K of RAM. But I bought a small flatbed plotter and wrote a driver to intercept the printer output and convert it to plotter commands. The result was some pretty nice multicolor plots for my term projects. I wound up turning one project in composed entirely of computer output (printouts and plots). The next year I asked the professor if I could have it back for my portfolio, but he said that wasn't possible. It was against school policy, and besides, they were up for accreditation, and he kept it to show off as an example of a "typical student's work".

I knew I would never be allowed to, just too damn exy. Eventually I got a second hand Sinclair ZX-80 from a distant older relative. Though was hard to use cause we only had one tv.

Also I built an interface that drove an IBM 360/370 console printer.It's all still in my loft, apart from the printer which was too heavy to get up there, so that had to go.Bletchley park wanted it, but I said no as it would just sit in a cupboard for many years.

I kept minor differences as one, the spacecraft is by name. So one for Soyuz and also not one for voskhod because it was just a stripped down vostok.Also no Starliner because it didn't bring the crew home.Next one is probably SLS in February.

In those days, a few missions past Apollo 11, most of my friends didn't really care. It was just a personal thing for me.In the much more recent "Two truths and a lie" business icebreaking game, one of the truths I've used is "I have touched the hand of the human who has been further from the earth than any other human in history". Apollo 13's trajectory behind the moon was further from the earth than any of the other Apollo missions.
