H8D Utility

[Norberto Collado]

I’m using H8D Utility from Les’, and I need to get the path to find an empty CP/M H8D image. I found the HDOS empty H8D images, but I cannot find the CP/M ones or do not know where to look.

I believe this zip contains empties for both HDOS and CPM.

Actually those might be for HDOS only. One thing you can try is using the H89 emulator to era *.* a disk image and save it out.

Norberto,

  You can use cpmtools to create h8d images:  http://www.moria.de/~michael/cpmtools/

You'll need to add this to the diskdef file:


diskdef h8d
  seclen 256
  tracks 40
  sectrk 10
  blocksize 1024
  maxdir 32
  skew 4
  boottrk 3
  os 2.2
end

Chris had provided this info a few years ago.

I went to the site and jumped around to other sites and I was not able to find the cpmtools zip file.

It was at the bottom of the page: http://www.moria.de/~michael/cpmtools/cpmtools-2.15.tar.gz

That is assuming you have linux or mac os x, where you compile it easily. A windows executable appears to be available at: http://www.cpm8680.com/cpmtools/cpmtools-2.9-Win32.zip but I've only built from the source for my mac.

Thanks!  I downloaded the Windows version, and started a CMD section. Also I updated the diskdef file. What is the syntax to create a CP/M H8D image?

 

[Mark Garlanger]

So it would be the mkfs.cpm.exe program. From the unix man page:

NAME
       mkfs.cpm - make a CP/M file system

SYNOPSIS
       mkfs.cpm [-f format] [-b boot] [-L label] image

DESCRIPTION
       mkfs.cpm makes a CP/M file system on an image file or device.

OPTIONS
       -f format
              Use the given CP/M disk format instead of the default format.

       -b bootblock
              Write  the  contents  of the file bootblock to the system tracks
              instead of filling them with 0xe5.  This option can be  used  up
              to  four  times.   The file contents (typically boot block, CCP,
              BDOS and BIOS) are written to sequential sectors,  padding  with
              0xe5 if needed.

       -L label
              Label the file system.  This is only supported by CP/M Plus.

Cool! That worked out fine! Here is the new image for CP/M.  Thanks a lot! J
