I have what appears to be another AES 5.25" diskette format. This is an "AES DATA" labelled diskette, hard sector. It appears to be 35 track, 48 TPI (no data beyond track 35). Looks like it might be MMFM, though fluxengine's mfmfm decoder seems to do a pretty good job on it. Bits are laid down backwards, as in other AES formats.
Fluxengine's inspect shows 4us clocks, and it does appear to decode, somewhat. I can see sequences of 0's preceding sectors, and the data _seems_ correct-ish, but no regular sector marks as in other AES formats.
Help would be appreciated. Attached is cylinder 0 read using:
gw read --drive b --track "c=0:h=0" --fake-index 300 aes-cyl0.scp
on a 48 TPI drive. There is no data on head 1 on the disk. Because this appears to contain a legal document, I don't think I should post it all...
