I did think of those. But I never thought of them as having an OS. Just the hardware and a firmware language interpreter.
The list there is much smaller. Just the ZXSpetcrum that took me through the 80s until close to the end of the decade when I got my first PC. ZXSpetcrum emulation is one of my longtime passions and I do play its games still today. That console had a great impact on me and is responsible also for having me choose the path of a developer. On it I learned to program BASIC and Z80 assembly, from paper magazines.
I do also remember owning one of those old cartridge gaming consoles of the 70s. I know today it was probably a Coleco or Magnavox. It was bundled with tons of games on two cartridges. Like 100 games. Most being variations on a theme. But those machines where not built for user interactivity. Definitely they were not early PC philosophy. The ZXSpetcrum was most definitely!
