For mentioned adapter I suggest remove both header lines and solder new 2x4 headers in middle holes , compatible with dip-8 size. Header pins recomended with smaller diameter which fit in dip8 socket. Scan connected holes to socket contacts.
14-D1 activated..
pin 6 = 1.18v
Something wrong. Voltage schould be >4V or ~0V.
14-D1 activ (with OE-24 and 32-Vcc)-measure voltages on 4503/4 and 5 (top chip 4503, closest to 4069), ZIF32/14, 93Cxx/2, 24Cxxx/6, 25Cxx/6
Activate/deactivate 14-D1 to confirm voltage changes on listed pins.
Waiting your check and results.
