Sorry 'bout that, I should have been clearer.  I don't seem to be able to 
run Ultimuse3, I assume its out of memory system memory.  I don't believe I 
can make a boot disk using drivewire, that leaves enough memory to run 
Ultimuse3, I would have to leave sacia, t2.dd and probably 2 or 3 other 
things which would severely cripple it for any other use than running 
Umuse3 with drivewire.  Probably not impossible to do, so I may try.

I have spent some time playing with the mouse while studying my current 
version of l51.defs, and I do not see any obvious mistakes.

The location of the mouse packet I am referring to can be easily seen as 
its defined as being at $10EC in system ram, by vtiodefs_cc3, so if dmem 
and dump are loaded into memory, a loop can be constructed to give an about 
once per second update printout on screen, of the packet buffers contents.
According to that, my joydrv_6551L.sb is doing it right.

What puzzles me, is that the SS.Mouse call returns a $3C long buffer filled 
with every conceivable item about the mouse, but so far I have failed to 
find where in the SS.Mouse call, the translation between the 8 byte wide 
buffer specified in vtiodefs_cc3, using Bruce Isteads byline as the 
originator, and the $3C sized buffer that is returned by SS.Mouse and can 
be accessed via varname,x in subsequent programs that use a mouse.

I did look at the src for SS.Mouse in 2008 when the question came up as I 
was writing joydrv_6551L.asm, me asking me WTH? but that code and the $3C 
buffers contents aren't even playing the same game. let alone in the same 
ball park.  :(

I guess that is the price I pay for trying to fix Tandy's crap so it 
actually works!

Cheers, Gene
