Technical Specifications
In my opinion the SA860 is the best 8" drive I ever had. Stupidly, I destroyed my first drive myself through inattention. I am still annoyed!
I have been able to buy a second one, but this one does not work properly; I have not been able to find the error yet.
Signal lines
In principle, the signal TG43 (TRACK GREATER 43, WRITE CURRENT LOW) also appears on the Shugart 860. The drive is already so new that it also allows internal support via jumper and the external line no. 2 is not needed. But this is not true for all 8" drives.
Other drives with an internal TG43 jumper are the Tandon TM848-1E/2E (do not confuse with the older TM848-01/02) and the Mitsubishi M2896-63-02M.
The basics for connecting a 8" floppy drive to a DOS PC are described here. And here are my pictures.
