Here is my collection of AT&T 3B1 stuff. We have the enhanced diagnostic disk. We also have a patched install disk that allows the emulated 3B1 to boot all the way up.

Next is a disk image of maximum supported size (175 Megabytes) with the foundation set, FIXDISK 2.0, the terminfo end user package, the development set, the documentation set, the curses development set, and the encryption disks, pre-installed.

I have added a bunch of stuff to the above, yielding this disk image. The full list of what's been done is in this file. This disk image is a large, empty file system for use as a second disk.

Blah blah stuff
