Do you have the rest of it?Here is the datasheet
I appreciate you taking the time to check.Checked my meager inventory, I don't have that one.
Thats itDo you have the rest of it?
Or is it really only one page?
Sounds like a cool chip. I'd like to read about it but I couldn't find a DS either.Thats it
Kinds similar to the Namco 07xx, but with fewer outputs.
You could probably cobble a replacement together with a few GALs if the datasheet gives accurate timing diagrams.
If you really want to design replacements just buy one from @mhcapps and make a couple measurements to get the divide ratios and timing for the various outputs. It wouldn't be too difficult.That's why I was asking about a datasheet. But I didn't find one yet.

Or just save the effort and buy the real part from me. Unless you just want to do it for fun and to learnKinds similar to the Namco 07xx, but with fewer outputs.

Yea, that would be the "...and timing for the various outputs." I mentioned in my post. You could always punt and use RS-170 timings since it's designed for NTSC.The divide ratios are trivial
The position and width of the sync and blank would need to be measured.
