is this possible? why would anyone want to do this? well, i used to have a commodore 64 with a color monitor. i bought a tv-tuner so that i could use it as a tv. i then gave the computer and monitor to my daughter to use at school. she didn't want the tuner. now i have a toshiba 1100+ and a cga monitor and would like them to play together. do adapters for this exist? thanks for the help. -geo --- George D.

CGA monitors are digital and TV is an analog medium, which makes them
mutually exclusive. If you want to watch TV with a maximum is 16 colors,
so be it.
The only computer monitor that can be used as a TV monitor is an analog one,
like VGA monitors (EGA is also digital, but 64 colors). To use a VGA monitor,
the monitor MUST have a composite video input or you MUST have a NTSC to
RGBrgb converter.
In other words, no, you can't use your CGA monitor as a TV monitor.

Well, actually there is another possibility. There are a number
of companies that make combo rgb/composit/TV units. I have
a couple made by Sears that work quite well. It is basically
a 13 inch TV with a front panel switch to go from TV, to rgb,
to composit input. It has a green screen button, and another
that compresses the screen in the vertical direction about 20%.
Makes cga text easier on the eyes. It has pretty decent resolution
and is impressive at 640X200 16 color EGA mode. Great thing
is the price was less than $200!

I have a Radio Shack monochrome composite CGA monitor and a Magnavox
RGBI/composite CGA monitor that I have used as a TV monitor with my
VCR. The monochrome worked OK. I primarily use it as a monitor when I
record programs on my VCR. The contrast was hard to get right. The
Magnavox supported RGBI, composite and had a switch for TV mode.
Though I could never tell the difference when the sitch was on or off.

It has come to my attention that there are some CGA monitors with composite video input and well as the DB-9 TTL input. OK, so I have never seen one. So, a clarification is needed, since the poster didn't say if it had a composite video input or not. I suspect not, since the poster would have seen the connecter and tried the tuner with it. If your CGA monitor only has the DB-9 connector, it is a digital monitor only and cannot be used with analog video information. If the CGA monitor has the DB-9 and RCA composite video connectors, hook up the tuner to the RCA connector and set a switch someplace for that input and you will be in business. Sorry about the confusion, but I really do suspect that because the original poster only saw a DB-9 connector, the question got asked of the net. -- harvard\ att!nicmad\ Vidiot ucbvax!uwvax..........!astroatc!brown rutgers/ decvax!nicmad/ ARPA/INTERNET: brown%astroatc.UUCP@spool.cs.wisc.edu

Well, mine says "TV MONITOR - TOTAL VIDEO SYSTEM" model # 21353.
There has been at least one update to this model since I bought
mine, mainly slimming the case and coloring it black.
