Thank you. As it happens just this week someone on facebook sent me a copy of a tpdd1 disk. It hasn't arrived yet, so I don't know if it's actually a good copy yet, but I assume it will be fine.
So I am probably set. With that I should be able to proceed with trying to devise a way to take an image and then re-create a disk from the image, that doesn't require anything more special than the drive itself. If it's convenient and your m100 and tpdd1 aren't packed away in storage I may ask you to coroborate what I see just to verify that the disk I got looks the same as yours before I go assuming it's a good reference to work from and redistribute. But only if it's not a project, because realistically, if the disk I get boots and does IPL, then it must have been made by the backup program and is probably a proper copy. Thank you again. -- bkw On Sat, May 4, 2019, 1:06 AM you got me <ven...@hotmail.com> wrote: > Brian K.
