notice the origin of the Commodore MM.1:
Santa Clara, California.
gives you a first impression of the huge Minuteman I.
of the calculator could be easily seperated.
Everything feels solid and heavy with the Minuteman 1.

MM.1 reveals a big surprise:
The printed circuit board (PCB) is identical with the Bowmar 901C
calculator (right) and carries even the PM901-400/E designation.
