[comp.sys.atari.st] The ST, the IBM, and Mac FDHD drives

mg20+@andrew.cmu.edu (Michael Paul Greelish) (10/15/90)

I write for the alternative newspaper here. When I do my article
writing, I like to do it at home on my ST. I submit my articles on disk
to the Mac-using editors because retyping s**ks, and the paper is
desktop-published.

How do I do this, you ask?

Well, since the ST writes disks in (damn close to, but not exactly) IBM
format, what I need is a Mac that can read IBM (MS-DOS) disks. The new
Mac SE's and above have FDHD drives that can do this.

At first I couldn't get the Mac to read the Atari/IBM disk. I did
everything: 720K format, 360K format, etc. It seems that the Atari
writes disks just different enough from true IBM format to screw up the
(very primitive) Apple File Conversion Utility.

The solution? Format the disk you save your data on on the FDHD-equipped
Mac. The Apple File Conversion Utility lets you do this, just pop a
blank disk in and it will ask you if and how to format it. Select MS-DOS
format, at whatever density your ST can handle.

This disk will be accepted by the ST, although it will be a little
different from standard ST format (ex. the Mac will *INSIST* you name
the disk; this name will appear as a file on the ST desktop (leave it
alone!))

I basically translate ASCII text, command codes really screw the
conversion process up. I go from Word Writer ST (ASCII saves) to
MacWrite format. Data such as spreadsheet stuff might be possible.

Anyone with any response/advice/similar situation can email me here at CMU.

You are right: Mac AFE does not read ANYTHING but a 200% IBM format!

Another solution is to use ibmfmt.tos from Moshe Branner: it works
perfectly well with Mac AFE. Putting a MS-DOS boot sector with DCformat
(3.0) is of no use because DCformat keeps the original size of FAT, which,
on ST is 5 sectors and on IBM is 3 sectors! I think AFE tests this info.
