Yodobashi Formula-1 and Lotharek HXC SD MAX

[Pyewacket]

I have a Yodobashi Formula-1 CP/M System.
Drive A and B are builtin 5.25" 40 Track drives. The system has a 34 pin floppy connector
on its back to connect two additional drives (which I don't have).
I connected the emulator via a 1:1 cable to the system.
How do I have to set the DIP switches to have the emulator as drive C and D?
I tried DS2 and DS3 but it does not work.

You have to make a cable which put driveselect from c and d to a and b for the HxC.

As you have to add a cable with 3 connectors after the 2nd conenctor you can cross the driveselect stripes. Cut a and b and behind that solder c with a and b with d select.
