Re: Mystery (RGB?) card

Heh, cool.

..you have the cable, too. I just have the card.

I never figured out exactly what it was but I was more along the lines
of it being a laser disc controller.

However, it doesn't have any type of either serial or video support
logic on it. Just all TTL off the shelf stuff, and a lot of it at
that.

The two bank dip switch and with you having that cable, the 9 pin
makes it suspect for a video card from physical appearance.

Look at the pots, see where they go to on the header, and see if they
fit into where pins 3,4,5 and 8,9 are on the 9 pin.

That would be R,G,B and H,V sync accordingly.  thats 5 signals.

Thats als the primary color points for EGA. But with a 1989 date code,
even though VGA was only about two years old it had already spread
like wildfile through the PC clone manufactures, particularly those
that became known as the "gang of nine", when in 1988 they trumped
IBM's proprietary microchannel bus with EISA.

On  the other hand, LaserDisc was fairly popular in that era and if
the Apple II had any remaining niche it was that. A lot of kiosk
setups over the years were developed using an Apple II as a driver for
a laser disk and touch screen. Which is another thing I thought that
card could have been with the amount of pins on it's connector.

I never did dump the ROM and see what it might have eluded to being.
Heck, sometimes there'e even ASCII that gives it away. D'oh! Gonna
have to find it and see about doing that.
