Hi Since there was a bunch of CPM-8000 stuff showing up lately, I've been trying to get it to work on my Olivetti M20 ( what the release code is to run on ). The code I got was originally from 8 inch disk. I have both the 8 inch disk images and the files recovered but contained enough information to build a boot disk. As near as I can tell, the code was to run on a 5-1/4 inch disk and not the 8 inch. That is what I have been working on but I've reached a stumbling block. It seems to be CPM related so people that know CPM should be the most help ( I mean, know what directory structures should look like and how the disk blocks are referenced, not just, I can use PIP or ED ). I've been building a boot image from the files and what I understand of how CPM should look. I've got it to the point that it runs the low level bootstrap code but fails to do the final load of CPM.SYS. I know it is running the bootstrap because it prints the error message that it has an error in opening or reading CPM.SYS. This is only in the bootstrap code. I have the files on my PC and I've written some code to build the image. I then copy the image to a disk for my M20 and try to boot it. So far it doesn't seem to get the CPM.SYS file correctly. I can't tell if it is an issue with the directory I built, the file location or something about the file itself. I hope one of you can help me by looking at my image file and confirming that I am building the directory and file correctly, for a CPM type file. Thanks Dwight
