u Using the C=128
Computer with a VGA Monitor
After the sad news about C= Scene's VGA
adaptor, it now appears there is still
light at the end of the tunnel for
users wanting to use C= machines with
Newer monitors The information below
was taken with permission from the
following website

It seems that this user has managed
what many have tried to do for a long
time, its not a neat solution but does
appear to be a working solution to an
old problem Using the C=128 with a VGA
Monitor
It's now possible to use a C=128 with a
VGA monitor without too much hassle or
expense. Below is the configuration of
my system, allowing for use of both 40
& 80 col video modes at the flip of a
switch:
RTV Veg Lite Composite-to-VGA converter
(for 40-column mode).Appx. cost: $40-60
Highway CGA (RGBI)-to-VGA Converter
(for 80-col mode). Appx cost: $90-140
Basic wiring:
40-column video is routed to the RCA
jack on the Composite-to-VGA converter.
VGA output from the Composite-to-VGA
converter is routed to the VGA bypass
connector on the RGBI-to-VGA converter.
The RGBI-to-VGA converter connects
directly to the 9-pin D-Sub connector
on the C128 for 80-col video. The VGA
monitor is connected to the VGA Output
connector on the RGBI-to-VGA converter
There is a bypass switch on the back of
the RGBI-to-VGA converter that, when
used with a Composite-to-VGA converter,
allows you to toggle between 40 & 80
col modes. The switch is in an awkward
location, though (in the back between
the power & bypass cable connectors),
so for convenience I've added a toggle
switch to the front of my project box.
Thanks to members of the C128 Alive!

For information and suggestions instr-
umental in making this this possible.
Special thanks goes to Mangelore for
providing info necessary to overcome
the lack of Intensity pin on the RGBI-
to-VGA converter, thereby allowing all
16 distinct colours!
