K7 file extension

Tape Image File Emulator

Files with the extension .K7 are image files of tapes used by 'DCMO6' an emulator program used to reproduce the following systems:

* Thomson MO5NR
* Thomson MO6
* Olivetti Prodest PC128'

DCMO6 emulates Motorola 6809 microprocessor and MO6 hardware,
allowing to run MO5NR, MO6 and PC128 programs on any PC.

.K7 tape image files are usually created by playing the magnetic tape using a bog-standard audio tape player through the line-in on the PC sound-card and recording the input as an audio file which is then converted into a tape image file using a conversion program.
