[Coco]: help changing screen resolution on OS-9

[John Guin]

Hello all,

I finally got my SCSI drive from Cloud -9 up and running.  I've hit a weird
problem, though.  It's got Nitros9 on it, and is set to run at 80 column
width.

My monitor is pretty poor, and I'd like to change that back to 40 upon boot.
I'm facing 2 problems, though:

1.  I don't know which startup file to edit to change it to 40 columns up
boot.
2.  Since I'm not familiar with OS9, I don't know which edit commands to
use.

Since I am also having a hard time reading the screen, can anyone guess at
the keystrokes need to change this setting (at least to 40 columns first:  I
can probably figure it out from there).

Thanks all,
John Guin
