I have a first-model MT-32 (no headphone jack). It chokes on certain SysEx commands created for later-model units which are spaced too closely-together. Is it possible to upgrade the ROMs to the 2.x ROMs from the later board to fix this? I'm not sure if the later ROMs are dependent on the later hardware; maybe the relaxation of the 40ms spacing between commands requires more RAM or other hardware differences?
