I've run a cross a CGA/multi-I/O card that I've never seen and can find nothing about.

As you can see from the pictures, it has a 9-pin video output, 2 game ports, a mono/colour switch and a bus mouse port.

I'm guessing that the mono feature would be Hercules?

This must have been a killer card back in the CGA gaming days.

Anyone know anything about this card? With the jumpers on the current positions, everything seems to work.

Posting closer clearer pictures of the chips and the identifying marks might help.

Well, all the chips except the SMD are standard, off the shelf TTLs.

The SMD has the following on it;
6612
Japan
812006VI

I found it a little less than useful.

The only markings on the whole card, front and back, besides the component designations (C6, R4, etc, light pen, mouse) are K. C. KS-4 and a hand written serial number.

The RAM are two 4464s.

Not a lot of information.

Jaton used a similar chipset here: http://www.vgamuseum.info/index.php/news/item/500-unknown-6612

Maybe an avenue of investigation.

Yeah, it's a place to start. Thanks.
