I think the tally is now 15 - found another that I thought you might want. There is, I am sure, some redundancy in files over the lot. But since it is rather a bother to compare and consolidate, ... There is a peculiarity in the DOS disks running on my machine that I don't really understand the reason for. It may also be true on yours, so be wary! The situation is this. Only the one marked System Disk will boot on my machine. The other ones that carry the system get into IO.SYS and then an Interrupt Trap stops the process and displays registers. My first thought was to GENSYS the system from the good to the bad. BAD IDEA! The result was that the good disk became bad in the same way, and the bad was worse - it just hung. What does work and what I would recommend as a *very* early course of action for you is to grab a handful of DSDD disks, come up on the system disk in A:, and FORMAT B:/S each of the DSDD disks. This will make them each bootable. Then using DISKCOPY, make working copies of each one that I am sending. Preferably, several of the System Disk. With that safety margin, you can experiment to see if your machine acts differently than mine. I'm afraid you are on your own as far a copying the P-System disks is concerned. I haven't had the chance to progress that far yet! Good luck! Don Maslin
