I have the Morrow Design docs, but the software discussed is all for
CP/M. This box came with a bunch of BASIC and ASM programs that look
like they are intended to patch N*DOS for the 8" controller. Cannot
find anything out about them, though, thus the comment about trial and
error.

Memory says Morrow never bothered with NS*dos only CP/M but it tould be
iteretesting to see
otherwise.

I misread. A DD controller will only boot DD and the SD controller will
only boot SD.
The DD controller can read SD disks.
Also there is such a thing as NS* dos being SD only as earlier version
didn't know of the
DD controller. I believe the DD controller came after V5.2.

Huh. Don't recall seeing anything about that, but will re-check.
Thanks to Dave Dunfield's fine work, I have
my Horizon system up and
running!
One thing still puzzles, me though: Is it possible to create and
boot SD diskettes on a DD system? When I boot at DD and bring up
NST, it cheerfully writes a SD diskette from an image. However,
that image will not boot. Should this work?
Yes, however you must forst format the disk as DD and when you do the
copy you must also specify DD for the destination. Its in the
horizon DD manuals. Next hurdle is getting the Morrow Disk Jockey 8"
controller hooked
in. Some of the diskettes I received with the unit (none of which
boot) have Basic and ASM programs that look like they're intended as
support for the DJ controller. Without documentation, this is going
to take a bit of experimentation, I think.
Get docs as that will save a huge amount of time. They are likely on
Bitsavers or other archives.
