[Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.

Then, an Arduino board might ... A0 (originally used as an analog input) doubles as a digital-to-analog converter (DAC) pin that acts as an analog output. D10 and D13 (usually digital I/O pins ...

A 12-bit analog DAC is also provided on the new board. To ensure maximum backwards compatibility with existing code examples and tutorials, significant efforts are being made on the software side of ...
