This is a Macintosh (the original) emulator. It emulates the CPU, video hardware and floppy disk (partly) well enough that you run the original OS and applications on it.

And it runs on a Raspberry Pico ARM microcontroller meant to turn on lights, read sensors and control toys.

@jannem @mrundkvist The microcontroller in the power brick of a MacBook is about as powerful as the original Macintosh

Same thing with the ARM controller sitting inside my keyboard. True, it does need to do both usb and Bluetooth; still, even the smallest, slowest Cortex m0 is really *way* overkill for the job.

@fl0und3r @jannem @mrundkvist my colleagues used to apply for faster and faster computers and I used to reply that if they wanted faster computing they should go and learn to type first. The slowest interface was brain to keyboard. They were two finger typists with RSI

The only hardware upgrade I need for my old laptop is three replacement key caps: for the left hand CTRL and SHIFT keys and the letter "a".

@fl0und3r @jannem @mrundkvist @marcpalmer curious what a more modern power brick is like. The one used as an example is quite old at this point.

@ellenich @fl0und3r @jannem @mrundkvist @marcpalmer interestingly, it predates both their USB-C chargers and the switch to GaN.
