Read and write North Star Advantage disks from PC

This is an overview of how to use the rudimentary software I've written to make disks for your Advantage from disk images, if you don't have a bootable disk for your machine, and also how to make disk images from disks to archive any software you do have. North Star machines are notoriously hard to transfer data to because of their hard sector disk format.

Main bugs in my code are poor handling of reading damaged disks, and apparently (as I found out today) a failure to return to track 0 before starting to write. Whoops! Guess I better get on that.

Currently I have:
- Old and new revision (ADV and ADV-3) machines
- HDD adapter and associated software
- 16-bit adapter, 64KB daughtercard, and MS-DOS
- Serial I/O (almost all of them have one of these)
- Some water-damaged brochures and documentation

I would like to find:
- Anything, anything NorthNet related pretty please!
- Parallel I/O card and documentation
- A physical copy of the Technical Manual to obtain a better scan
- Any later revisions of the tech manual which might cover the ADV-3 mainboard
- Any software packages, especially with documentation, even boring business ones
- Brochures and communiques
- Anything I haven't thought of

Even if you aren't willing to part with it, please comment here or email me (dualityk, gmail) if you have something on the list; maybe we can figure out a way to share it with the two or three other people in the world who might care!

Hello from Beijing, China. I just got two of them on the way, which is working with Chinese language feature. Thanks for your great work for transfering data from and to the FDD, I'd like to learn the detail to live these two old computer.
