Yep, that's definitly part of the DVG, and has nothing to do with the speed
the game plays at, rapid fire, etc. I believe I've got one at the shop that
I can get the PROM images from if you need (if I haven't already archived
them).
Atari probably designed it because they couldn't second-source the 7497, or
there was a temporary shortage. I can't see it being any kind of cost
reduction - even back then bipolar PROMs were more expensive than just about
any TTL IC. I wonder if Jed Margolin would know the real story - might be
before his time though...
