I would have liked a Microprofessor but never had one: A friend brought the LED version home from college to do a project, which was to write a functional 'digital clock' program for it (in assembly language assembled on an Amstrad CPC and then typed into the MPF by hand). We focused on getting the basic hours / minutes / seconds to increment and decrement and display correctly: He was going to add the time setting interface and 'increment time at one second intervals' bit later.

If I did come across one I would pair the MPF-IO board with that but in the meantime it provides what Maplin never really did supply as far as I know: A decent range of general purpose I/O for the Maplin system.
