Check the DDC line and its peripheral circuits
(IC1701 (EEPROM) and its peripherals).
Check the DDC line and its peripheral cir-
cuits (IC1501 (EEPROM) and its
peripherals).
Does the signal come from pins (34 and 35) (CLK±), (31 and 32) (D0±),
(28 and 29) (D1±), and (25 and 26) (D2±) of IC1702 to pins (39 and 40),
(43 and 44), (47 and 48), and (51 and 52) of IC1510?
Does the signal come from pins (34 and 35) (CLK±), (31 and 32)
(D0±), (28 and 29) (D1±), and (25 and 26) (D2±) of IC1507 to pins
(58 and 59), (62 and 63), (66 and 67), and (70 and 71) of IC1510?
