MODIFY ALPS DF354H DRIVE FOR ATARI USE
MODIFY ALPS DF354H DRIVE FOR ATARI USE
I tested one of these drives today. It supports 11S/83T & 22S/83T (Tested in FCOPY PRO)
DEFAULT IS DS1.
CHANGE TO DS0 FOR ATARI USE.
I ALSO SOLDER A 0805 10uF CAP ACROSS THE 5V RAIL ON ALL MY DRIVES>
LOCATION FOR HD WIRE SELECT
WARNING! DO NOT UNDO THESE SCREWS! I PUT SOME THREAD LOCK ON THEM JUST TO BE SAFE!
If you do, it will upset the head alignment and you will spend the next 2 hours trying to get to all aligned again

Interesting.
What is the cap for exactly ?

Smoothing on 5V rail. A lot of drives have electrolytics which dry up. So I just put a 10uF across the power and have done with it all.
