Sorry, but that doesn't make sense - 10x512 DD

at 250kbps / 300rpm - standard double-density. PeeCee HD drives
will do it at 300kbps / 360rpm. I am not aware of any DD formats
that use 250kbps / 360rpm, Although ImageDisk should handle this
if the drive can ... (Chuck?)
I think I've got one in 8" that does this--it's single-density, so so
the data rate really is 125Kbps. If you're really curious, I can dig
some and find out. The 2.8" sorta-floppies used in the SCM PWP's ran
at a data rate of something like 62.5Kpbs, but I wouldn't consider
that a "real" floppy--more like a streaming tape laid out on a floppy
cookie.
