Master Unit for Nominal Test Execution and Relaying
It will be a prototype for testing controller and interface designs. The name comes from a crazy dream I had many years ago which involved building a computer and calling it that so I made the name fit. A munter is also a term for a really ugly female
OK, munter is 'merry' in norwegian, and I suppose it also could be a merry chase getting things to work?
Z80 is a great MCU, I did many projects with it in the late -80s.
I just wondered about your serial interface, I suppose it is for a tape interface? Why not use a flash chip instead to save code in? If that is the intended use.
The serial interface is for first time programming which can then be transferred to any ROM devices (I dont have a programmer so this does the job instead).
