[comp.os.cpm] Osborne Screen

Could someone please tell me if and/or how to change the osborne to
display more than 40 columns when using an external monitor.

I am posting this for a friend, I know very little about the osborne.

The "stock" Osborne displays up to 52 columns. There is a program called
SETUP provided with the Osborne on the Utility disk which will change
the number of columns you get before line-wrapping. A few public domain
programs perform the same function.

HOWEVER... for more than 52 columns your text will go off the edge on
BOTH the internal and external monitors. The only way around this is to
get a HARDWARE VIDEO UPGRADE, like the one from Nuevo Electronics. I
don't know what it costs now, but it's probably close to the market
value of the Osborne itself. I faced the same dilemma and chose to keep
my O-1 at 52 columns.

Even with an upgrade (at least the OCC factory upgrade), the Osborne external
monitor attached to the "MONITOR" port will not display 80/132 columns without
an extra doo-dad.  Only the composite RCA jack outputs 80/132 column video.

The adaptor, which I received from OCC with my newly upgraded tan case Osborne,
seems to convert the composite output to whatever the Osborne monitor uses and
adds the power lines.

BTW, doe anybody know why removing the little dummy plug from the "MONITOR"
jack with the power on fries its innards?  The manual warns about that, and
once I accidentally did it, and sure enough, the video subsystem died.  How
come?
