I'd redesign the whole driver board before reverse engineering that thing.

To design the G08, someone sat down and said: "How can I turn a raster
monitor into a vector monitor, while doing the least amount of work?".

I'm pretty sure the above quote of mine was in reference to the
pincushion correction circuit I used in the ZVG, which is also being
done in the G08 specialty chip. The offer still applies. I came up with
a pretty nice replacement design for the MC1495 used by Atari for
pincushion correction, that would also need to be done by any Sega
replacement part.
