I am sure you can create something like this (but the opposite). That should be easier and cleaner than trying to find and fit a 3.5 mech. in the case front openings.
Edit: I also found this:
"my notes are somewhat incomplete (nothing for pin 7or 8 )
If I recall correctly, if you fly the ground, you only have to move a couple pins to put the chinon connector right on the even pins of the floppy drive.
14 pin Chinon connector <-> PC 34 pin floppy
14 <-> 30 read data
9 <-> 32 side 0 select
1 <-> 8 index
6 <-> 14 drive 0 select
10 <-> 10 motor on
2 <-> 18 direction in
3 <-> 20 step
5 <-> 24 write gate
12 <-> 26 track 0
13 <-> 28 write protect
4 <-> 22 write data
11 <-> any odd pin (ground)"

Just another question here... Has anyone considered an external option?
I'm only asking because I have some other non-Atari ST drives that I'd love to be able to use on my 8-bit if it's possible... For example, the Future Systems GTS 100 and 1000.... Both would be great to use on the A8 (or failing that, a way to take the mech out of the GTS 1000 and use it in an Indus GT as a 360k drive but still have the track display and the buttons.....)

Today I tried to use a cheap and more common Chinese Samsung 1.44 mech. From an old Compaq computer with the new sf551 board by Dropcheck. It worked.
First I needed to locate the drive select and put in DS0. After that was just a matter of connecting but data and power cable. It worked at the first try. I formatted a diskette in mydos to 720kb without problem. I also wrote the DOS files so I was able to boot the computer with the new formatted disk.
I can confirm, that this regular inexpensive 1.44mb drives can be used with Atari: format and read without problems at 720kb.
I even took an old used IBM 1.44mb diskette and covered the HD hole and it also worked.
