Hi Guys, I have posted the update to ImageDisk which allows it to work with Head/Cylinder values on a per-sector basis if needed. I have also posted a number of additional ImageDisk format system disk archives. I have also added a new page which describes how I constructed the adapter for the 8" drive, and the cabling system I use to allow the external drive to be easily removable and to co-exist with an A: internal drive. I have provided photos of the various constructions as well as descriptive text. There is link to my "Connecting 8" and external drives" page near the bottom of my "disks/software images" page, which is accessable via a link near the bottom of my main page.
