You must remember that the M100 was created at a time when it was "the norm" to use flat ribbon cable to make connections to computer peripherals. This was true for parallel and serial connections to external devices (modems, printers, plotters, etc) as well as connection between two computers. The serial cables that Radio Shack sold were this type to connect a M100 to a Model III or a Model 16.
This was also a time before rigid adherence to much of the FCC testing for spurious emissions and susceptibility were required for computers/peripherals and inter-connect cables (the sort of test failures that killed the Model I and created the Model III). An IDC (Insulation Displacement Connector) version of the DB-25 variety with a flat ribbon cable connects just fine to the opening on the M100, and was what was expected to be used. The problem now days comes from the use of the shielded cables that were introduced with the IBM PC/XT/AT computers. These were required to pass the FCC testing, and are the style that are available today. Most have molded "hoods" that vary somewhat in size, and were not designed to be used in a shrouded opening. When the M200 and T102 were created, the shrouded opening in the case was made bigger to accommodate these shielded style cables.
