For completeness and avoidance of confusion, the machine shown on my site is the Ai Electronics model ABC-24. It has dual 5.25 disks.
I also have its bigger sibling, the ABC-26. The -26 has essentially the same electronics but has dual 8 inch disks. I believe that the software I have found is ABC-26 so I will need to set up for reading/archiving 8 inch media.
Since the machines are otherwise very similar I am hoping that much of the ABC-26 environment will be able to be run on the -24. Hoping....
