Q: are you going to continue to expand the collection of images,
and perhaps take over where Don Maslin left off?
If so, read through to the end!

IIRC, the Ensoniq Mirage had mixed sector sizes.
There is apparently at least one BMC if800 format that can be done with
I had some difficulties with "automatic format recognition", particularly
from used reformatted disks. I wasted some time when somebody sent me
single sided disks that had been formatted over PC 360K disks, which
hadn't removed the old content on the second side, and with HP 3.5"
diskettes that only rewrote the first 77 tracks, etc.
Because I was only dealing with file transfer, I never bothered to even
list which of the sample format diskettes that I have are system disks.
Would you like me to send you some sample diskettes to look through?
