Tell HN: The stuff I learned to program on

I noticed, we are telling us that all the time, even when it is borderline off topic. So I thought let's just have this fireside chat for once… What toolchain started you off as a coder? What was particular awesome about it? Here's mine: Triumph Adler Alphatronic PC https://vintagecpu.wordpress.com/royal-triumph-adler-alphatronic-pc/ I thought the amber colored display was more awesome than the usual standard green ones. Softwarewise the graphic commands to draw lines were a cool addition to the BASIC. Much like Turtle graphics. Later on the CP/M cli was pretty exciting. Exiting the editor to start the linker and compiler… Ah, and there was an event listener who could detect when a disk was inserted into the drive, if memory doesn't fail me.
