Hi there...
If you look at any of the early (1976) Radio Shack TV Scoreboards, they all
contain a skeet/shooting mode with light gun. The chip contained six
games...four variations on ping-pong (doubles/hockey/soccer, etc) and two
shooting variations. Look at the Wonder Wizard Bulls-Eye and others for
examples of this. The AY-3-8500 was developed in the Scottish labs of
General Instruments in 1975. Magnavox was somewhat involved in the
development process, some of their sub-contracted engineers did visit the
labs to test the chips. Aside from them, Radio Shack, Coleco, and Radofin
were among the biggest clients. There was _huge_ demand for the chip, so
much so that they (GI) couldn't fill all of the orders. Many of the smaller
clone-makers went under as a result. The only "clone" chip I am aware of
was developed at National Semiconductor, they marketed a machine called the
Adversary in 1976 containing this technology...
I have more info if you're really interested.

Okay, I'll check those out. What I was interested in was what variants
exist, how it was programmed, and if there were any clones. There's an
obscure Commodore Pong machine called the TV Game 3000H, which sounds a bit
like the Magnavox Odyssey 3000, except the TVG 3000H has a light gun mode
which I haven't seen on any others (except maybe the Telstar?).
Any ideas?
