This one doesn't quite fit with the Miyata serial numbers I've collected. Please check to ensure you've transcribed the serial number correctly. M would indeed reperesent a 1984 Miyata build but the samples in my database indicate that the 2nd alpha character was not used until the 1985 model year. The confirmed 1984 model Miyata builds in my database use an M followed by six numerals. If it was a 1985 model, it shouldn't start with MA, as that would represent the first two weeks of 1984.
