I would be interested now that I have a P-code card you will just need to tell me how to get it to run!!
Well, let's see what I can do during the upcoming holidays. Now I'm away on a business trip, so there wil be nothing for a while.
I did check it a while ago, and the files seem to be there, in working order. My copier consist of assembly support for four things:
- Read a disk track, regardless of content.
- Format a track, with any kind of sector numbers.
- Read any sector number from a track.
- Write to any sector number on a track.
Then there's a Pascal program, which uses these functions to read a disk track, analyze it, format a copy of it, read data in all sectors on the track and create copies of these sectors in the track on the output disk.
If I remember correctly, this was enough for Advanced diagnostics, but for Explorer the program had to be expanded to also handle unformatted storage in the tracks.
I'm pretty sure it worked with the WD 2793 disk controller chip on the CorComp card only.
I made this program before I had any knowledge of anybody else doing the same thing, so there may be better ways to copy the disks, created by other TI users. I know of come copiers that could handle one specific copy protected disk only. Like being able to copy AD, but nothing else. The good thing with my program was that it could handle any irregular sector numbering (a common trick to fool normal copiers) on its own, and create an identical copy.
