The software situation is quite amazing – not so much for the quantity of it, but for the associated manuals which are substantial.
All the original disks have been imaged. The Flight Simulator II disk is copy protected so an IMD/IMG is not good enough; an SCP is required. The Overhead Express disk that i grabbed from the web needs to be written from the IMD; it is not enough to just grab the files.

A full list of software is here, but it is not easy to tell if all of these are OEM versions and to what degree they may have been modified to work with the One:
The DG OEM version of wordstar always changes to the MONO screen mode when it executes which means it can’t be used on the external CGA screen. The non-OEM version works in either mode.
I have not found a CP/M-86 disk although i have seen it mentioned in forums. There is a CP/M programmers guide amongst the manuals that i have.
Some of the Data General communications mention a version of Unix but i have not found that either.
Most of the manuals do not seem to be online so i have some scanning to do!
Many generic IBM compatible apps work fine.
