Could you possibly look to get some of the floppy controller improvements merged?
There's no reason they shouldn't be if they achieve more accurate behaviour.

Did you get anywhere with this?UgoR934 wrote: ↑Wed Dec 30, 2020 12:34 pmSorry, not trying to be nitpick.. but just to discover something every day: back in the day, I thought this PIN was needed to format a DD 360K 5"1/4 floppy disk inside a HD 1,2M floppy drive. Is it true or false? I could imagine that 3,5" drives can just auto-configure themselves by checking the second hole, but I can't remember "an hole" for 5 1/4 HD floppies (instead, I could remember that you can force HD format on a SD, of course with disasters coming in seconds).Oh, and that argh ao486 note: density select pin is not needed for that. It should work both for DD and HD disks in DOS.
Also.. THANKS for your updated pinout!
Finally - again - a request for help.
I checked out CD4050B schematic (the only chip I have to do level conversion here):

I looked at I/O schematic (I think you also pointed out) and the output seems open-collector. In input, I don't think I will need anything to get a stable logic. So my proposal is this one (ex. for a single input and a single output):

Do you think it's ok?
To be completely honest, I just can't figure out how to integrate it properly and not compromise any other MiSTer functionality.retrorepair wrote: ↑Wed Apr 21, 2021 1:18 pmCould you possibly look to get some of the floppy controller improvements merged?

Yeah, from what I understand its right now a custom version of WinUAE that does this, but if the creators of that can explain how they got it to work, I suspect it could also be done for FPGAs... well, that would be pretty awesome if it could anywaybazza_12 wrote: ↑Fri Jun 04, 2021 7:20 am I did comment to Neil on Twitter, if the drive worked on MiSTer but he said as it was a WinUAE device it wouldn't work. There must be some jiggery-pokery that can be done to get it to work. It would defo scratch a retro itch to have a floppy drive that could read Amiga (or even ST) disks
It could, but I am asking whether it has to or maybe already has been, to get the current solution to work.retrorepair wrote: ↑Fri Jun 04, 2021 6:55 pm The core's floppy controller I believe would be replaced by this so shouldn't matter
Does the current Minimig pull the low-level floppy code from Replay? If so then that gives you .scp image file support where you can load copy-protected disk images. I am working on the FloppyBridge for WinUAE. There are already a variety of other emulators and utilities that support using the SuperCard Pro hardware to read/write disks directly.Caldor wrote: ↑Fri Jun 04, 2021 7:07 am Yeah, that new development that allows floppy disks to be used with WinUAE ought to be something that could be used for the MiSTer as well, and I am guessing it could be used for more than just the Amiga core but giving it different firmwares to run.
I am certainly thinking about getting a Greaseweazle now. I have the SuperCard Pro and that was the main reason I did not invest in one yet, but... there is just something nice about having direct access to physical floppy disks.

After I finish adding Supercard Pro and HD support, I'm planning on picking up the gauntlet on the MiSTer. Won't be for about a month or so, and I don't even own one yet.
Just thought i'd give you the heads up. Not wanting to tread on anyone's toes, looks like there has been some interesting progress which I can take a look at and am willing to work with whoever wants to! I just want to help to work towards a great solution.
blame floppy swapping.. but we all know

Great to hear this news. (it's Richard from Heber here - we talked a few months back) - Super excited you are investigating the Floppy support in MiSTer.
If we can assist with any testing or hardware prototypes / help, just let me know.
The MiSTer Multisystem is launching shortly, that has a number of possible expansion add-on ports we could use if the Arduino/serial/USB route does not give you a way forward for the MiSTer and Minimig core - direct FPGA connection or via the USER port may be a viable option.
Cheers,
Richard.
Nice I have a SuperCard Pro, so I look forward to test this. Also got a GreazeWeasel on the way. When I first heard about this working with WinUAE, my first thought was that it might also work for the MiSTer or at least a Raspberry Pi. That certainly would add something extra interesting to my Pi + Keyrah in an Amiga 1200 casing setup, if it could also have a floppy drive added to it.RobSmithDev wrote: ↑Thu Aug 26, 2021 11:45 am I know this thread has been a little quiet.

Code: Select all
ln -s /dev/sda /meida/fat/games/AO486/USB_FLOPPY.IMG
Unfortunately, that won't work on Minimig core. These USB floppy drives don't understand Amiga (880KB) disk encoding format. However, It may work on the Atari ST core which uses the same 720K format as the PC.NightShadowPT wrote: ↑Sat Feb 26, 2022 6:08 am Would really love to get my PC disks working with AO486 and my Amiga disks with Minimig
