Just read it through, the only thing I would suggest adding is a section with a more elaborate description, including circuit diagram, of the power arrangement needed to power the SC/MP 1, with Phil's 'Proper' PSU with a centre tapped transformer and +/- regulators and the simple / crude alternative using only 12V and a Zener both shown. Leave it up to the reader to decide which one to use.

This exotic early power supply requirement may be foreign even to many people who have quite a bit of experience with microprocessors generally.
