Question about the ibm "CGA COLOR GRAPHICS" card. I have a cga card
and also have a mono graphics card. The mono card will not run
any of the 'cga required' software (ie games). Can I use a color
Television as a cga monitor? If so, how do get the card to emulate
an 'RF Modulator' signal so the TV will receive the signal?
The card has a composite signal phono-jack in the back. Will the
card as it exists produce a 'RF' signal with some jumper settings?
Can a composite to RF signal translator be created through hardware
means?
Thanks in advance to anyone that will respond to my question.

If your lucky enough to find a smart salesperson, he'll sell you one for about $25. Plug one end into the composite-out jack of your CGA card and plug the other end into the antenna (or cable) connection of the TV.

You must use a RF modulator to convert the composite signal (from RCA jack of CGA card) into RF signal before feeding it into your TV (which is set to either Channel 3 or 4). Here are some of your solutions: 1. You can buy a stand-along RF modulator from Radio Shack for about $25, or you can get one of those match-box sized internal RF modulator for $5 to $10 and solder it inside your PC. 2. If you have a VCR, you can use it to do the modulation by connecting the composite signal to the "video in" jack at the back of the VCR. 3. Forget about color TV, use a Princeton MAX-12E monochrome monitor which is capable of displaying CGA output signal in 16 grey levels. You can manually switch the monitor input cable between mono card and CGA card. 4. Forget about color TV and CGA card, run SIMCGA which emulates CGA on a Hercules mono card. However, only some well-behaved games will work. (e.g. Art Of War, Bushido, Alley Cat, Cross Fire, Big Top, Zaxxon, ...) Please be advised: some mono programs cannot run properly when you have both CGA and Hercules cards inserted. Microsoft "Windows" is one of them.

Plug one end into the composite-out jack of your >CGA card and plug the other end into the antenna (or cable) connection >of the TV. Before you do that, walk to the back wall of the Radio Shack. Find the spot where they have the surplus "special purchase" stuff. Next to the C-64 keyboards should be some surplus TI 99/4A modulators @ $4.95 each. All you need is an RCA plug and a 6(?) volt AC adaptor to convert it into a nice general purpose RF modulator. Full notes are included with the modulator and a converter cable can be easily produced with a minimum of hardware ability. -- Name: John Ruschmeyer US Mail: Monmouth College, W.
