I would love a version of Pico PIO with analog out (along with a limited integer ALU, or perhaps just shifts and some logical ops). A fast DAC should be cheap in silicon, right?

The pimoroni servo2040 uses the PIOs to PWM 18 servo channels: https://shop.pimoroni.com/products/servo-2040?variant=398005...

I'm annoyed at the power arrangement on the board but they're fun to play with.

That's a nice usecase. Servos are slow mechanical things.

I wanted to make a CGA/EGA-to-VGA converter, possibly combined with a scandoubler. Maybe it's still possible using resistor arrays on the output side.

Have you seen gbs-control?[1] It's not exactly what you're trying to do, but maybe close enough?

(Very late, sorry.)

I hadn't. That does look very interesting. Thanks!
