Note: In a previous post today, I offhandedly said "I can actually make my own CPUs, not good ones". On rereading, I realize this may overstate my ability, as it implies I can make mediocre CPUs. In fact I can make fricking terrible CPUs, and only in HDLs. The only time I have actually created a circuit which executes a stored program was in ABEL, an HDL so antiquated we called the device it ran on a "CPLD".

I aspire to someday make a mediocre softcore CPU. That would make me very, very excited

@mcc i happen to have come across this 3D-printed vacuum-fluidic / pneumatic thing today. The state can't be read by the thing itself so it isn't capable of being made into a CPU (without another innovation) but it feels like it needs to be set here
