Sears Electronic Basketball has a 28-pin IC from GI labeled 69-11557. The PCB traces match a PIC16C55, and I was able to dump its ROM with my rig. I compared the dump to Tandy Electronic Basketball (PIC1655-051) and they are nearly identical; only 19 bytes are different.

Along with these 2 games, and the 4 games and 2 devices listed in the skeleton driver hh_pic16, I've got 5 more PIC1655/1650 games dumped:
1650-133 Tandy Baseball
1655A-053 Atari Touch Me
1655-024 generic Mattel Football clone
1655A-033 Toytronic Football (3rd pic)
1650A-144 Tandy 2-Player Football
