Have you looked at Cpmtools?

If you already have an image of a bootable disk for the target system,
and you already have the files you want to copy onto a bootable disk
for the target system, you should be able to use Cpmtools to copy the
files onto the image of the bootable disk. Then write that updated
image out to a physical disk. Then if all goes well that should be
the last time you need to use the Image Disk setup.
The only tricky part about using Cpmtools is that you usually have to
create a new disk format specification entry in the diskdefs file,
which can take some work to figure out, but shouldn't be too bad.

Ahaa!! I forgot about CPMTools. Haven't been feeling too well lately, so
I was starting to grab at straws here. I think the diskdefs file may
already have the 8" 77 track format. I'll dig into it and let you know
what I come up with. :) Thanks!
