I examined the logic schematics of Amutronics TV Ping Pong and schematics indicate of having a SWA (slide switch A?) with option 11 and 15 and also a SWB (slide switch B?) also with option 11 and 15.
I don't know if that is a misprint in the logic schematics Rev. A sheet, but that is what the sheet has printed. I am not sure what the "Second switch, the one on the right, says S -- T" does because it is not on schematics for Amutronics TV Ping Pong. So it does likely go to Amutronics TV Hockey or maybe something else not yet verified.
The Amutronics TV Ping Pong schematics have a Rev. A printed because it appears Amutronics updated the pong clone to have altered circuitry to have "side walls" drawn on the tv monitor as schematics describe. The authors probably meant "side walls" being the top/bottom boundary walls being drawn since that was a feature supported in later pong clone games.
So this could mean emulation of both Amutronics TV Ping Pong and also Rev. A of Amutronics TV Ping Pong since the updates are also printed on Amutronics TV Ping Pong logic schematics.....that is if anyone really wants to cover emulating both versions.
