[net.micro.cpm] IBM CP/M Format

cem@intelca.UUCP (Chuck McManis) (11/29/84)

The version of MS-DOS I have for the Zenith 150 comes with a utility
called RDCPM.COM. The purpose of which is to read CP/M-86 files on the
floppy. The $65,535 question is what is the format for this floppy
Specifically :
How Many Bytes/Sector ?
Interleave Facter ?
# of tracks before the Directory ?
A Parameter Block for it would be ideal.
Total storage of this format ? 180/320/360K

RDCPM for the Z-100 is designed to read Heath/Zenith CP/M and CP/M-85
formats (It was available before CP/M-86 on the Z-100).  Heath has
used 2 CP/M formats, 16*256 byte secotrs / track and 8*512 byte
secotrs per track. Apparently RDCPM figures out which you are using.

It doesn't work on the IBM, I tried.
