The frequency of QD disk is well above the 22khz (this generally something around 100Kbits/s). i am not sure that the tapuino can deal with this.

Anyway i have now something working to dump/write and simulate QD disk drives (and ANY others kind of floppy disk drives :wink: ) without any issue. :D
This floppy simulator/reader/writer is based on a de10-nano board and a buffers piggy-back board. This one will be sold by Lotharek.

I can right now make some QD disk dumps. Let me know if some of you are interested to send me some disks.
Are you continuing to have success with this? Is there a release date for the product?

Thanks!

Is 10 pin more difficult as 32 or 16 to handle.

I have a question : When i will release something for the QD emulation, do you think that you will able to make the specific ribbon (wiring,soldering,...) or are you waiting for something "plug & play" ?

I will make any cables necessary. I am also happy to help with further development, troubleshooting or support.

Thanks!

Yes. Most of the product is already there since this is based on a de10-nano board. The piggy-back board prototype is quite simple to make if you are able to solder some ic on a board.

Fantastic!

Do I get the piggy-back board from you, or do you have Gerber files?

How do I get your code to the de10?

Thanks.

(less buffer ic are needed if you only want only QD Disk emulation.)

have you a de10-nano board ?

I will purchase a de-10 if you are confident that QD emulation has a good chance of success.

Will you be able to share your code?

Thank you.

I will publish some videos to show you ;).

(btw which machine to you plan to use with this ?)

The binary / bitstream yes, but why do you want the code ?
