Under WHAT operating system? Under OS-9 level ONE I know nothing
about what options are built in to the sytem… there probably ARE none.
All that will offer is the worthless color composite striped signal
on the monochrome monitor. Tho a patch or module for OS 9 level
one may be available eventually. Under OS-9 level TWO I am told
there will be a mode command that will allow you to set the output
of the composite port to monochrome. Under RS BASICK, we will
eventually find the appropriate SHADOW REGISTER in the base page
that can be POKED in order to set up for monochrome output.

Dale Lear has both a CoCo3 AND a monochrome monitor, and he may be
able to enlighten you further.

That’s user name DALELEAR.

    Marty,
    Since most of my work will be under OS9 Lv II, it looks as if I’ll
    be ok, though we all know that since shack has once again FAILED to
    provide for monochrome composite, it will be up to us
    to do it!. Geez with the proper patch for BASIC and OS9 shack
    could sell its VM-1 Composite monitor along with the CoCo 3 whne
    they can’t seel them the new RBG monitor. Oh well, I just
    feel that shack will NEVER relaise that marketing
    potential!!

    I fully agree that Radio Shack has made a big mistake
    in NO
    T emphasizing the option of using a monochrome monitor
    with the Coco 3. But do note that at the hardware level,
    between the color /monochrome bit in the GIME, and the
    options available by choosing the correct foreground and
    background color, the CoCo 3 is (wiht proper software set up!)
    quite capable of producing a decent (tho not spectacular) image
    on a monochrome monitor. I KN
    OW that… I’ve seen Dale Lear
    set up a very nice monochrome 80 col screen on his.
