There's a comment in the floppy emulator changelog about the AFI format supporting hard sector emulation. If I am able to generate an appropriate AFI file, can the HxC (STM32 USB) properly act as a hard sector diskette? If it can, where can I find documentation for this format?

There are a number of us out here who would like to use the HxC with Heath and Northstar computers. I have documentation on the track format for both of these.

I will gather it and either post here (if allowed) or make available on Dropbox.

Since the message board will not permit any meaningful attachment (PDF rejected), I'm sending it to the e-mail address you have provided to others for this reason.

Notes:

- The textual description of the sector preamble has two typos. There are 33 bytes of 0, not 16. Sectors contain
512 bytes of data, not 256. The text was written for an earlier FM scheme, I'm guessing.

- The byte following the sync character (0xFB) is an address formed as (sector + (16*track)) MOD 256.

- Encoding is MFM

- Physical track layout is 0..34 on side 0, then 34..0 (logical 35..69) on side 1

Please let me know if more information is required or you want me to do any testing. I own (and know how to use) an 18-ch logic analyzer and can capture activity at the interface from a real drive and/or the emulator.

Any news about this topic?
Are there hard sectored floppies like the ones used in the Northstar Advantage supported?
I would be really interested

Thanks and regards!

Still would be great to have hard sector format support. Is there a chance this will ever be added?

Hi, Jeff. I have (2) Gotek units and one SD Rev C. I would like to use floppy emulation with my Heath H89 and Northstar Advantage. Information on both formats is available (and I have posted some of it here in the past).
