[Coco] RAM disks for the Nocan board, Collyer Vavasour, and MESS systems

[Robert Gault]

I am in the process of writing a new version of the OS-9 program Rammer 
to access the extra memory above 2Megs for Paul T. Barton's Nocan boards 
and for the MESS and Collyer/Vavasour emulators.

The versions for Paul's boards are not ready for distribution but I have 
working versions for MESS and the Collyer emulators. These new RAM disks 
do not us any OS-9 memory for the RAM disk and very little memory for 
the driver/descriptor. The MESS RAM disk is 6Megs and the Collyer RAM 
disk is 14Megs.

The size of the RAM disk is controlled by the descriptor. So it is 
trivial to alter the number of cylinders with dmode or dEd.

If there is any interest in this new Rammer, let me know. I'm not sure 
of the best method of distribution or interest level.
