David, First, congrats on the Linc-8, I look forward to helping you load it for VCFE if you ever decide to do that. Second, thanks for the OSI disk diagnostics. My 8” drives are giving me issues, and Bill Dromgoole has been coaching me via email on them. We both want to get our 8” drives working with a data separator (Klyball D-13). Bill got his working with a Gotek/Flashfloppy emulator also. Hope all is well with everyone, and you stay safe! -Cr
