Can’t be worse than my original plan, which was to use a Viking SCSI controller and hack all the things to support it. Bit fiddling happened in the driver, in exec mode. I actually had a hacked standalone DSKDMP that knew how to format “packs” on it, but it was so dog slow I never bothered writing a timesharing driver for it, instead waiting until someone came up with a better solution.
