Well, thanks Ingo for the information. And so, one more nice chess program added to my collection!

Should you like to give it a fast and easy try: https://lanale.de/kc85_emu/KC85_Emu.html
then use your browser search on the page, keyword Schach (of course!), click on the screenshot and there you go.

or

get the JKCEMU software (java) from here: http://www.jens-mueller.org/jkcemu/
plus the video chessmaster game from here: http://kc85.info/index.php/download-...ss-master.html
and so you can run it locally on your PC, which is what I did:



You may need to resize the JKCEMU window: Menu Extra-Ansicht
Select the emulated hardware (I chose KC85-4): Menu Extra-Einstellungen, select, activate (Übernehmen).
Now you may save this setting as a profile; name it accordingly. I used kc85-4 as the name, this created the profile file prf_kc85-4.xml (you can check the target directory in the rightmost tab (sonstiges) of the settings.
I would suggest to create a small .bat or .cmd file in order to automatically launch the emulator using this profile, such as: start jkcemu-0.9.3.jar kc85-4 (adapt the version number to the one you downloaded, mine is rather old - but fine).
Once the KC85 runs, you get the standard KC-CAOS menu. Load the chess.kcc game file (menu Datei-Laden). Type and enter CHESS, you are done.

Moves are input using basic algebraic format like E2E4.
Commands can be input using only two chars:
NE new game
LE'enter'0-7 --> level
CO swaps color with computer (exits referee or selfplay modes)
CA quits
BO set board / exit board setting
thanksfully, entering a position is not done the same way as the chess computer, it is more usual. Funny enough, the software uses english for commands , but the pieces names are german (this puzzled me for a while before I found this out!).
e.g. : BE4 adds white bauer at e4 square
'space'E4 removes the piece from e4 square
-BE4 adds black bauer at e4

Time ago I used the JKCEMU for the GDR chess computers SLC-1 and SC-2, no more as they are now available thru Franz's CB-EMU.
But I still use it for the SC-80...
Have fun!
