The drive select jumper just links one of the drive select pins on the
interface connector to the appropriate internal signal. So if your drive
doesn't have jumpers, all you need to do is make up a cable between the
controller and the drive that (in this case) takes drive select 0 from
the cotnroller to whatever select pin (probably DS1) that the drive does
respond to. And link all other signals straight-through.

By "twisting" three wires:
10 - DS0
11 - GND
12 - DS1
you get what you want.
This is how IBM MFM drives had their twist done versus the floppy that
twisted more lines to twist into it the motor on line.
Please note you CAN NOT use any PC twisted cable for a standard floppy cable
but it is easy to "un-twist" part of a PC cable to use as a standard floppy
cable for a lot less $ than buying the components to build your own.

If that is the question the answer is yes. (use one
hole media aka
720k).
I have a few pounds of DSDD 3.5" media.
What I think I *don't* have is a 3.5" drive that can be jumpered to ID
0.
