software, as found here: Here is a thread on my site about my Pentium III system dedicated to imaging disks, plus a link to the class notes from the talk at the VCF East last spring: http://vintagecomputer.net/browse_thread.cfm?id=561 I am using a generic Pentium III, which will handle the Adaptec card you have in place of the Catweasel I have.The drive controller of the Pentium III has no issues with a 5 1/4" HD drive, which with an adapter can mimic a 77 track 8" drive. Note that I have a dual boot system, Dos 6 and Windows 2000. Works perfectly. Very little I can't image with this that is image-able. I also intend to put in a Quad Density drive, but I have not gotten around to it yet. The quad density I believe will look to the Pentium Bios as a 720 3.5" drive. In short, make your life easy, use a Pentium III with a compatible BIOS. Bill
