Proposed memory map by ExSilent has issues with current Intricon circuit's memory map used by Audina.
Possibility to shorten YearCode (to 6 bits) by ExSilent, and move it by Audina to Word3 (and move Word3 to Word1, ie basically swap fields).
Possibility to move ModelCode to Word2 by ExSilent, so Audina can use it as usual.
