A good strategy, very helpful: a little more detail than I had off the
top of my head, but along the lines of what I'm thinking.

I wouldn't have to worry about the data coming off the tape, since it's
checksummed. It with either load or it won't.

My immediate problem: my old floppy drive is out of alignment so I can't
read anyone else's disks, and my old OS-9 Level II boot disks are lost
in the garage.

Hence my request for someone to send do the DSKI$ thing on track 34 of
one of their diskettes and send me those bytes.

Thanks for the helpful response,
