I've put together an image which I am still working on, primarily for my II Plus, which contains some useful tools. Right now the starting point is the ProDOS 2.4.2 disk from John Brooks' website:https://prodos8.com/releases/prodos-242/
Combined into the Blank drive with firmware file provided in TJ's repo (https://github.com/tjboldt/ProDOS-ROM-Drive) I pieced it together using the instructions for Bitsy Bye (again, from John Brooks' website).
The result is an EPROM image you can burn to your 27c801 for your TJBoldt ProDOS rom drive which boots into Bitsy Bye and contains not just BASIC.SYSTEM but also Copy II Plus and ADT Pro. I thoght that even though I am still in progress with this, it is enough that some other folks might find it useful.
There is the majority of the EPROM space left still (easily 800k) so there is room certainly for other things. I am certainly open to suggestions for additions, especially if you know the utility will run from a ProDOS volume.

If your II Plus does not have a lowercase ROM installed, TJ's copyright disclaimer will appear scrambled (not a problematic issue, do not panic).
