[comp.os.cpm] Disk formats

Does anyone know the difference between various CPM disk formats ?
I am using an Altos 586, which I recently discovered can read
double-density (as opposed to quad or 96 tpi) disks.  This worked
for a disk that was in IBM CPM-86 format.  Does anyone know if this
is the same as (or close enough to) Kaypro 2 CPM ?  Kaypro 2 CPM is
the only 5-1/4" CPM format for BYTE Listings on Disk.  If I can
read that format I may get some of those disks.  The Altos manual
doesn't mention the MODE command I used to read the IBM disks, so
it obviously doesn't tell me what other disks I can read, if any.
Any info. will be greatly appreciated.

Previously, when Simtel20 was available from BITNET, I was able to download
a file containing numerous entries of disk formats for many machines.  I
cannot recall the name for the file, but it seems to be rather complete.
Someone should load her down, I could always distribute it, but that would
be troublesome.  If you do want it and don't have access to SIMTEL20 or
the BITNET server, I can scrape it up and send it to you.

Cheers.
