Subject: MS-DOS Emulator V2 coming soon - Info on DPHs and DPBs needed

MS-DOS Emulator V2

MS-DOS Emulator's V1.03 (demo/test) is to be followed by the
full-featured V2 soon (I hope at the end of July - the work has been
seriously delayed due to moving into a new house and the hard work
related to that). A demo/test version will be posted on the net as soon
as it will work. I intend to distribute the V2 as shareware, since it
required some 6 months of work (mainly on evenings and during weekends -
the temporary abandon of the work after V1.03 is not included).

For making the emulator as much machine- and CP/M version-independent as
possible, I would be very glad to get information on the format of Disk
Parameters Blocks (DPBs) and Disk Parameters Headers (DPHs) used on
different systems. My machine is a Commodore 128 with CP/M Plus. The
only requirements to a system for running the MS-DOS Emulator are (1) to be
able to read MFM diskettes with 40 tracks and 512-byte sectors and (2)
to do no translation of the sector and track numbers. The second
condition is not observed by some CP/M Plus systems (Commodore 128 is
among them) and this is the reason of my request for information on DPBs
and DPHs. Any BIOS sources (if not copyrighted) are also wellcomed.

The MS-DOS Emulator V1.03 is a demo/test version running only on
Commodore 128. The emulator allows the user to handle files on MS-DOS
diskettes directly with CP/M's commands and programs. It makes,
actually, the CP/M to recognize the MS-DOS format. The MS-DOS formats
supported depends only on the possibilities of a certain system to
read/write the MS-DOS diskettes.
