How to modify CP/M diskimage?

MIRKOSOFT · 18. Juli 2009

Hi!

I was searching net for program which can modify or create CP/M disk images.
I have some images in D64 format which e.g. DirMaster can view, but not correctly also not editable...
Can anybody help me? Knows anybody of any program which can do it?

Why?

I downloaded extracted CP/M files for Commodore 128 and I can not work with them... 'cause I cannot transfer it to diskimage or real diskette...

Thanks for every reply.

Here's a page with a kind of complicated procedure how to transfer single files from an ordinary disk to a cp/m disk using c128 memory:

... I want to add extracted files to CP/M D64 image or to CP/M image and convert it to D64 format...

Isn't it possible to use CP/Ms "pip" command to copy from one drive with a normal D64-image to another drive with the CP/M formatted disk? I would give it a try in the emulator.

I have only extracted CP/M files on PC-HDD. If I select drive as a folder, CP/M it recognizes not as a valid diskette, only prints "NO FILES".
This is the main problem - I need to have empty CP/M diskimage and a program which can open it and add files to this image, then transfering to D64 is no problem 'cause CP/M D64's are only with changed extension (but not all)...
Know not about any program to work with CP/M diskimages...

..how to add CP/M files to any empty D64 image? DirMaster it allows not. Know you an other D64 manager?

and.. VERY VERY THANKS!

Simply rename the cpm file to something.prg. After that dirmaster will allow you to copy it to the d64 image.
Then you can use rdcbm to copy that file from the cbm disk image to the CP/M disk image.
Rdcbm will ask you to provide a CP/M style name for the destination file, like" myfile.com".
It works - i just tried it.

...but when I start Binary Copy, after some seconds reports problem:
I/O error F1, PC=03F7
Program aborted
B>
(you can look at atached screenshot)

I did it with these steps:
1. Attach CPM/M system to #8 and boot
2. Attach CPMXTRA.D64 to #9
3. Change A: to B:
4. Run RDCBM
5. Attach blank.D64 to #9
6. Choice S - setup drives: CBMDRIVE=A/CPMDRIVE=B
7. Choice B - binary copy: select CBM file, set name of CPM file

Also - not info only for me - I found program which can add every filetypes to D64 image (still not found filetype which not) and its name is:
DiskImagery64

you can download it here: http://commodore.host.sk/dimagery64.exe

Maybe it can't find the source file since ".com" is not supported in CBM d64 images?
In the Source d64-image i named the source file "myfile" which is shown as "myfile.prg" if i list the directory. In rdcbm i entered "myfile" as source file name and "myfile.com" as destination file name.

Thanks for the information about DiskImagery64. Unfortunatly i can't access the file on your site. Message is "You don't have permission to access /dimagery64.exe on this server."

... I forgot to write correctly my steps:
1. Attach CPM/M system to #8 and boot
2. Attach CPMXTRA.D64 to #9
3. Change A: to B:
4. Run RDCBM
5. Attach source.D64 to #8
6. Attach blank.D64 to #9
7. Choice S - setup drives: CBMDRIVE=A/CPMDRIVE=B
8. Choice B - binary copy: select CBM file, set name of CPM file
? I/O ERROR

Also, DiskImagery64 is not accessible only by Opera and others than IE - copy link to IE and you can download it! I've got this same report, so I used IE to test...

See my last post. Maybe youll have to choose a proper name for the source file.

MIRKOSOFT · 18. Juli 2009

so, I tried three modes:
1.
source: demo.com / destination: demo.com = failed
2.
renaming files in surce D64 and
source: demo / destination: demo.com = failed
- but device A was active

3.
source: demo.prg / destination: demo.com = shows menu in any seconds
- but devices were not active

So, where can be mistake?

(if you want to try the same, I attached my files)

Thanks.

I had no problems loading the 3 files to a cp/m disk (see attachment).
Did you choose a cp/m formatted d64 image as destination to receive the files?

MIRKOSOFT · 18. Juli 2009

Really mistake was that I think that copy program format disk first...
So, now it works fine.
Very, very thanks.
This (adding separate files to CP/M diskimage) was my problem long time ago.
