I finally sat down today and hashed out a new prototype as I did not want to open my system up and get the one out I am using..
The Drive Select board functions as expected and it will stop all of us from cutting and making custom cables. a Standard straight through floppy cable (no twist will work).
I have tested this one and it works. My next step is to order some boards.
I have tested Reading, Writing and Formatting diskettes.
This just plugs into the back of the 3.5 drive and the cable from the FDC plugs in the other side. Select the drive # with the dip switch.
I included Drive #2, although you don't need this unit as a straight through cable will default to DSK2, i did it to keep numbering consistent for the dip switch.
