Hi Dave, John
just a quick update from me.
I have grabbed a few hours over the last couple of days to update the disk format to comply with cpmtools.
the changes are very minor, basically only the removal of one line of code (decrements LBA value by one) in each instance of the wrlba routine, this change
also removes the need for a modified MYIDEROM to serve as a boot platform, the CF disk can now boot directly from a S100 Z80 Monitor (option 'P').
I have started to update my documentation and remove obsolete information, hoping to have this completed by the end of the weekend when I wil upload a new ZIP file to my N8VEM folder and take down the old one.
The screenshot below shows the working CPM3 image, the files are as supplied in the CPM3 distro from http://www.cpm.z80.de/
The disk image was created using a combination of old and new methods, The Altair sim was used to create CPMLDR.COM and CPM3.SYS and these were placed into the disk image using the old method of sector copying. All the other files were copied into the disk image using cpmtools, the result being checked in a hex editor and all looks good.
one step closer to simplifying the process :-)
