@Deceptichum Among others, though my initial thought to put the Win key where the C64 has its "Commodore" key couldn't survive my pinkie's preferences.
There are also little notes of BBC Micro (I actually had three plates made, and #1 was partially BBC Micro themed) and Atari 8-bit, as well as a faintest whisps of MSX and Amiga. The idea was a liveable TKL with a vaguely retro feel.
