The Atari 800 was my first personal computer (i.e. one I had at home). I bought one when they first came out and learned 6502 assembler language and had a blast.
I had experience with assembler language on larger computers (DECSystem 20 and CDC 6400 in high school/, IBM System 360/44 in college then IBM System 370/145 at work) but having my own personal computer was incredible. Of course I moved on to the IBM PC when it first came out (and learned 8086 assembler language), and many PC compatible computers after that, until I retired and got my first iMAC (Intel x32 and x64), then now to my M1 Macbook Pro.
It was owned by the University across the street (Colorado State University). The mother of one of my friends was a Systems Programmer. We had a blast learning all about the machines.
