 That is problem #2 to be solved when needed.  Problem #1 is the nitro 
module doesn't do about 2/3rds of what its supposed to be doing, so 
thats the #1 fix.  With that working, it should be able to boot w/o the 
dw stuff.  Then, figure out what to do about the dw things.

One step at a time.

Some of our problem is likely the defs files we have. I've only played 
with one of those, I found an off by one in the bit position logic in 
L.51.defs and fixed that, what? 15 years back up the log?  Maybe more, 
when I wrote the serial mouse driver in frustration because the normal 
mouse driver has a random noise generator in it.  With the serial mouse, 
you get a button click exactly on the point of the arrow, not someplace 
up to 1/2" away.  Editing a multivue icon was suddenly a pleasure 
instead of one of those Excedrin headaches we're so fond of hanging a 
huge number on.

os9.d is either deficient, or there are unpublished details for system 
memory usage in the remainder of the 8k block the DP is in.  It could be 
there, but finding "unused" memory in there so the memory mapping for 
level 3 doesn't step on other toes, or vice versa.  I have been 
intending to turn on the listing, and assembling those defs just to make 
free memory hold up its hand & wave at me.

But my main interest these days is in CNC machinery, and the kilobucks 
worth of Mahogany I am climbing over, around & even under in the garage 
in the process of becoming furniture for my remaining 4 children, a 
parting gift I guess since I'm now 81 yo, and now know I will not, 
contrary to what I thought 60 years ago, live forever.  The tool 
changing hassle in the mill has got me designing an Automatic Tool 
Changer. I am spending as much time changing cutting tools as I am 
carving wood.  ATC's aren't normally seen until the hang tag says 
something north of 40 grand.  Sometimes waaayy north.  Above a million.
