I picked up a book around 1977 on the PDP-11 processor and worked my way through it with pencil and paper to understand the architecture when I was around 13. I saves up my summer job money and bought a used Commodore PET 2001 for ~$700 with cassette drive and 8kb and a green phosphor screen. I later bought an expansion for it that gave me 32kb. The PET's 6502 was simpler, but that DEC handbook and working out registers on paper gave me a strong foundation in computers. I realized computers would only be tools and always managed to take jobs outside of comp. sci. or IT, but always used a computer and programmed utilities for every job I had in any language I fancied at the time and throughout the years: C, Basic, asm (6502, PIC, Scenix, 68000, 8086/88, now ARM/x64), Forth, Lisp (Lush/Lush2 lush-users on Sourceforge with Yann LeCun to get Lush running, APL, J, Logo, Pascal, Factor, Java, Python, F#, now Rust, Odin, and J is still open on my desktop daily). I had in mind how people were talking about high-paying jobs if you learned WordPerfect, and it was "the future" back in 1991-93. I felt people were putting the tool before thought, intelligence, and process. I did dip into DBA and IT here and there for a little bit, but I thoroughly enjoyed writing embedded software for the window animation I was working on for a display company, and interactive prox switches on the store window at Sachs to trigger a pneumatically actuated Nutcracker to raise his arm and close his jaw and other fun kinetic pieces in the late 90s (Pre-Arduino saturation days - Parallax Basic Stamp, Scenix, PIC, and PCBs from scratch by hand with resist and etch). Kids loved pressing the Nutcracker switches! The reason I learned so much was that you had to go to the library, write a letter or eventually by the 90s email and user groups, and just plain figure it out through trial and error on your own. I had a VIC-20, Commodore 128, Amiga 500/1000, then a PowerPC Mac running Mach Linux in the late 90s/early 2000. I loved Commodore. It's a shame. They were the best option for the buck.

Kindred spirits, you and me. That PDP-11 put you on the right path, for sure.
