Ok, so another clue discovered:
1) Typing DX1:/Z "zeros" the directory on a
floppy.
2) Trying this on drive 1 leaves the floppy

work.
Trying DX0:A=DX1:MONITR.SYS/O does not write the boot block
A disk formatted and zeroed is not mbootable.
Since the source to FORMAT was included I thought I'd take a peek. It tells
the controller that is embedded in the drive "format that disk." and it does.
There is a slim changce I've got a "spare" 8" drive that I can use to
check
the alignment on my drive 1. Are all 8" drives the same on their connector?
(actually there are the NEC drives in the Chrislin box that aren't being
used at the moment.
If the NEC drives in your Chrislin box are similar to those in my NEC APC,
they are wired in a quite dissimilar manner. Mine are a 50-pin header
connector (ala SCSI) and the signals are to and from the ODD pins vice

What the heck is used for "delete" on RT-11?
backspace doesn't work nor
does DEL apparently.
If anyone remembers how to actually assemble something I'd appreciate it.
WHen I run assembl it gives a '*' prompt, to which I can type
DX0:SAMPLE.MAC and it will assemble it except that it doesn't recognize any
of the macro definitions because it apparently hasn't included
"SYSTEM.MLM"
or whatever it is.
