Good morning,
I would like to install a 1.44MB floppy drive on my mega STE but I can't find anything on the net for this modification.
I found this: https://www.exxosforum.co.uk/atari/store2/#0227
but nothing on the installation procedure.
Has anyone done this already and could tell me where to install this chip and if there are any other modifications to be made?
Thanks in advance.
Can all registered uses please login, even just for a few minutes..

Re: 1.44MB Mega STE floppy drive
Atari MegaSTE, Atari TT and Atari Falcon can handle normal PC Floppy drives. You must set der Floppy to DriveSelect 0 and you have to put in a Atari AJAX Floppy Controller Chip in. The DIP switch 7 set to ON select the HD Mode ...

OK thanks.
Does anyone on the forum sell this AJAX chip in Europe?
I saw that there were some on Ebay but the shipping costs are very high from the United States!

Check first to see if you have an Ajax already rather than buying one blindly.Raisin54 wrote: Thu Feb 08, 2024 5:54 pm OK thanks.

Also I've attached the PDFs for floppy and FPU install for the MSTE plus the GALs needed.
Should be of use to you.
