View Full Version : Connecting composite video monitor to a PC?

May 9th, 2017, 06:14 PM
I have come into a collection of old monitors (one of them is an Apple III monitor, the others are kinda generic looking). I think they are all monochrome in some form or another. They all appear to be composite video. I have a 486 sitting in my house with a bunch of free ISA slots. Is it possible to buy an ISA monochrome video adapter that has composite out? Unfortunately most of the ones that I found seem to use 9-pin?

Here are some cards I found on ebay (kinda expensive but just looking atm)

Laser EGA 4+ CGA IBM PC XT 8 Bit ISA Video Graphics Card 702098B 35-2238-30

IBM 8-Bit ISA CGA Video Card with Motorola MC6845P Chip (F5-1501982) (http://www.ebay.com/itm/IBM-8-Bit-ISA-CGA-Video-Card-with-Motorola-MC6845P-Chip-F5-1501982-/152517320141?hash=item2382bd9dcd:g:71sAAOSwDiBZENv Q)

I assume it's not possible to convert from 9-pin to composite via some kind of adapter...
