Sometimes I feel bad for kids today who experience computers that are so powerful that they are many layers divorced from the hardware. Long gone are the days when there was only the thinnest layer of BASIC between you and the CPU when you boot the machine. But then something like this comes along and reminds me that there is no reason you can't just fire up a 16 bit machine with a paper thin OS if you wanted. Not everything has to be a smartphone or modern system. My hat is off to the author for going a step further and building a minicomputer from scratch.
