This could work, but I can´t get to the menu...
I start Mame - Select New Maschine - Geneve 9640 - Geneve Boot Rom 1.00.
The emulation starts and it search for a dos disk, there are only two keys that work, space bar and the windows key.
Space bar takes me to Geneve boot menu and the windows key opens windows 10 start menu.
If I don´t load the Geneve emulation I can get to Input (this machine), but there is only the choice to return yo previous menu.
And this time when I start up Mame I get a few errors about 'version table' (1 - unsupported file format) and
LUA ERROR in execute_function: plugin/data/load_dat.lua:37: attempt to index a nil value (local 'stmt')
After I pressed ok three times Mame will start.
Made a try to install Mame again, but no luck.
