well, if you need any images, these are the ones I have. You will need to use the PDD program to make disks.

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 <[email protected]<mailto:[email protected]>> wrote: Brian K. White do you still need help on this subject?

White <[email protected]<mailto:[email protected]>> Sent: Wednesday, April 17, 2019 6:08 AM To: [email protected]<mailto:[email protected]> Subject: [M100] tpdd1 util disk Has anyone ever taken an image of a tpdd1 util disk? (using the drive itself I mean, not using something like kryoflux) I have found floppy.co<http://floppy.co> for tpdd1, and the full disk image for tpdd2, but not a disk image for tpdd1. I want to try taking a stab at coming up with some recipe to generate a disk from scratch. I have a tpdd1 but no original disk. I figure, if the image existed, I should be able write that image back to a disk using stuff that's actually already available now, and merely it just requires documenting the steps. It might be a bunch of steps, and tedious, but possible is infinitely better than not-possible, and tedious doesn't matter until after it's even possible at all. The M100SIG includes utils that claim to be able to do sector access and low level hacking/editing on tpdd1, as long as powr-dos is installed, and also includes powr-dos, and so it may just be a matter of working out the steps to go from scratch, like to get powr-dos installed using any number of ways, break up the image into smaller chunks that fit in ram, etc. Or maybe you can do it by just formatting and writing a couple files and doctoring the directory table a certain way etc, without actually copying 100k. Writing a pc util that just talks to the tpdd directly is another approach, but that is inventing something new, which may or may not work or be trivial. What I'm aiming for is, I think all the pieces already exist and just need to be strung together. Maybe this would make it easy to make a new simpler pc util by just recording whatever powr-dos does. -- bkw
