What I did with my floppy mod was to use motor on and set WP low when motor on=off. Maybe a tri-state buffer 74HCT125 would work as a simple mod...
simple with a bit of GAL code..
WP.OE = !MOT_ON ;
WP = 'b'0;

Well there ya go, 10 years ago...... I don't know if those mods worked or not. I remember a lot of people wiring up wires to the ribbon connector, mostly on a unused pin on the motherboard and claiming it worked.. of course it never will but lots of people did it. It may have come from Amiga guys, maybe it worked with Amiga, no idea.Bikerbob wrote: ↑Thu Dec 14, 2017 1:13 am Chris you even commented on the thread, it was her thread, its still up on Atari-forum. Where she did the one line from WP to pin 2. Several other people commented that it worked great for them.
I am looking to use this on the mega STE.. not an STF. SO the 920 needs that circuit? It is so confusing. if her mod was wrong, why has it not been taken down?
Which mod ? I only mod the drive select ID on them.
No other steps needed. TOS 2.06 in MegaSTE works differently compared to HD mods in regular STs, since it tries 8MHz and 16MHz and sees what works (i.e, whether the inserted disk is DD or HD). It does not use any HD detect lines from the drive at all (neither reading a value or setting one).exxos wrote: ↑Sat Dec 16, 2017 8:38 am What you/we was talking about was "media change fix". Which isn't required to get the drive working. It is recommended to do yes, required, no.
As for the Sony drive, and indeed other drives, you have to change the drive ID to zero to work on Atari internally. I use the MPF920 as its easy to change and drive works really well.
As for any other steps for getting it working on the MSTE, like adding the PAL, dip switch 7 etc.. That is all I know. I don't own a MSTE so never tried it personally.. So maybe someone else here can verify if any other steps are needed ?
