I use to have before the fire, a box full of about 50 different 3 1/2's
My eon's ago i was responsible for evaluating 3 1/2's for Tektronix.
Three different types, and you should have seen all the rev's Sony
went through.
The part I remember the most is the convincing the now loosing camps
use to try to put down the Sony design.
I'll see if I still have some of the doc's and such, if i do, I'll put
them on a web site.

Pete,
Thats great, thanks, if anyone has any SA300's for sale/trade please let
me know, thanks.

New subject: CP/M to DOS conversion programs
Are there any PC (DOS) programs that can
1) Read a CP/M disk
2) Save the contents, including the boot tracks to a DOS file (or files)
3) Format a CP/M disk
4) Write these files back to the disk, including the boot tracks?
I know there are programs that can do this for just the program and data
files but what about the boot part of the disk. Seems that info could be
saved to a file so that a bootable disk could be restored. What I'm basically
looking for is a program that can backup a CP/M disk (including boot
records) and later restore them to a CP/M disk that would still be bootable.
I have looked at 22Disk but don't see where it can essentially copy and save
a bootable CP/M disk. I have heard about SmartDisk and Media Master but
don't know if they can handle bootable disks so that they can be backed up
and restored to and from a PC (DOS).
Anyone know?
Thanks,

Most such programs are for the purpose of transferring the contents of a
FILE from one disk format to another. SOME also include the capability of
duplicating a disk, but often ONLY IF the system tracks use a similar
physical format to what is used in the data are (no single density boot
tracks, etc.)
Instead of looking at file transfer disk format conversion products, there
are a few that may be better suited for you.
Look at Teledisk.
Look at CopyII-PC (and at the "Option Board"), and at the
"CatWeasel".
Although most commonly used for unauthorized duplication of
copy-protected disks, it will duplicate many of the disk formats that are
physically possible.
Be aware that SOME disk formats, including a few hundred of the CP/M
formats, are physically impossible to read/write/duplicate using stock PC
hardware. The stock PC hardware can only do MFM with WD style sector
headers. Some formats, such as hard-sectored and GCR can NOT be done
without other hardware. Some other formats, such as FM ("Single Density")
or some invalid headers (such as Kaypro DS), can be done with some FDC's,
with some additional software.
WHAT CP/M format are you trying to do?

Thanks,
Sounds like what you need is teledisk. It reads the disk in a bitwise
process an
saves the image as a file that can be used to recreate the original disk.
You can
get it at ftp://ftp.rainingdata.com/freeware/teledisk.zip All you need is
a
drive that's compatable with the original disk(s).
Good Luck
Mike

good suggestion
but you need a DISK CONTROLLER that is compatible, NOT JUST DRIVE. For
example, Amiga (MFM, but without WD sector headers) and some Commodore 64
formats (GCR) can use very "ordinary" disk drives, but their disk
controllers are different enough that Teledisk can't go near 'em.

There are two major formats for Osborne disks. (and a few variants)
One of them is "double density", with five 1024 byte sectors on each
track.
The other is single density, with 10 256 byte sectors per track.
I'll look into TeleDisk and see if that will do
the trick.
The double density one might work.

I have tried 22Disk. I can take a CP/M disk created on an Osborne and read
and save files to a DOS file. I can format a CP/M disk for the Osborne and
copy files back to the CP/M disk. So, it looks like it's easy to read CP/M
disks on a PC without any special hardware. The only thing missing, that I
need is the ability to save the boot record to a file and restore it to the boot
track.
Seems like that is something that everyone that wants such a conversion
program, would need. But I can't find such a program.

Suggestion: Hex Workshop can open a PC's floppy drive as a physical object. That
being the case, and assuming the boot record is not enormous, I wonder if you could simply
reproduce such a thing manually, through direct edit of the disk's tracks?

Yes, IMWIN. (www.farumdata.dk/enimwin.htm)
It will take a photocopy of the disk, and copy the format information
(tracks, sectorlength,....) to the new disk.

Anytime a web site plays so coy about pricing, I know it will be costly.

You would be right, if you would have to buy it. However, as I have the
hardware already available, and it has been paid for by "commercial"
conversion jobs, I have no problem with helping people out, as long as I am
not flooded by it. In your case, it could be considered "last resort", as I
am located in Europe.
