It's all BJTs running saturated. There's maybe a couple of resistors that might need to get tweaked, and you'd want to use the 3.3V rail instead of the 5V rail

It's all BJTs running saturated. There's maybe a couple of resistors that might need to get tweaked, and you'd want to use the 3.3V rail instead of the 5V rail from the Pi.
The thing that excites me most is that it'd be super simple to make a revised version of the book that shows Pi pinouts instead of Vic-20/C64/BBC pinouts and kids could hack on it again. It's been a long time since there's been a really friendly all-in-one piece of computer kit where you could do that.
