My father has an AT&T 6300. He has disabled the indigenous video card and has
used other CGA video cards successfully. I recently acquired a true Blue
original IBM CGA card (full-card) because it is the only source of <<color>>
composite output that we could find for a reasonable price. However, when
we use the composite output to his Magnavox RGB monitor, we get only black &
white output. The monitor works fine with a different 9-pin CGA card.
A technician in California suggested that the "colorburst
frequency" needed to be adjusted on the "motherboard" to adjust the setup
to give color.
I have two questions that someone may be able to help us with:
1) is there anything else that needs to be done to use an IBM CGA card in a
6300 (do we need a bus corrector, etc.?)
2) I thought the colorburst frequency would be generated by a crystal. Can
this be adjusted, and if so, how and where?
We need color composite output to generate a TV signal for a VCR. We are
making titles for home videotapes. If anyone has suggestions on doing this
we would also be grateful. Thanks for any and all information.
