Interesting to see something that definitely used the Tarbell double-density controller! That's a pretty rare controller, and one for which I have not found a lot of extant bootable media/disk images. The single-density Tarbell controller was ubiquitous and common and sort of set the standard for 8" floppy controllers on S-100. Reliable as a hammer.
