The TNC MC corresponds to the TNC GC, but instead of the 8" driver and the FDC III controller, the FDC5 controller is used (there are three changes: a jumper in the address decoder changes the address from the original base address 0x60 to 0x70, and a change in the values of the two resistors that determine the amount of precompensation during recording )

Boot loaders on TNS-MC computers report as "DMF1>"
or "DMF3>". They install the operating system from 5 1/4" floppy disks.
The "DMF1>" loader is intended only for TNS-MC computers which
are based on TNS-GC, while the "DMF3>" loader is intended for
all TNS-MCs (including those based on TNS-SC).
The system is booted either by pressing the [0] or [1] key. It
it depends on which drive the system is inserted
diskette.
System diskette for TNS-MC with these loaders is not possible
however, be used to boot the system on TNS-HC. Each of these
because bootloaders are required by a different OSBOOT boot program.
For TNS-MC/W, the system assumes that the computer is not
not adapted to autoboot from a Winchester disk,
introduces in the same way.
The TNS-MC(/W) computer can be retrofitted with 8" units.
In this case, it is possible to use the INT module from the TNS-GC computer
and boot the system in the same way as on the TNS-GC.
