I recently obtained some pristine copies of some original Model II software that I went ahead and imaged and have made available here
https://github.com/pski/model2software
All of these have been tested on a Model II and work well. I plan to add to this collection as I come across more software or if I dare to image some of the older 8" disks that I have in my collection. I'm wary about ruining one of the few working TM848s I have. If you would like to contribute images to the collection, feel free to PM me and I will add them to the repository.
