On a whim the other day I connected up my A/// which has sat unused since maybe 2000-ish, and even then it was only probably powered up to see if it did anything after I was crashed into bringing it home.
Once the smoke had cleared from the 0.22uF cap in the PSU (and I'd replaced it) I set to downloading diagnostics etc with the help of ADTPro, worked nicely. Diagnostics fine, Utilities disk can see my ProFile card in slot 4 and even my 110V ProFile (off a step-down transformer) worked and eventually gave me a READY light!
Picking myself off the floor I figured it'd be nice to get the /// booting from the ProFile. Only it seems that you can't. Best you can do is use the 'ProFile Driver and System Utilities' disk to copy SOS files over and/or put PROFILE.DRIVER onto a SOS boot floppy.
I can't see an image of this floppy on either Asimov or apple3.org, just 'utilities' and 'profile driver' images. The ProFile manual implies that this is a single floppy that Does Everything.
Back in the day did people just manually add PROFILE.DRIVER to their boot disks?
Any insight appreciated before I give up and replace the failed ProFile on my Lisa
