SG1000-II with TMS9918A chip
Post Posted: Sat Feb 01, 2020 4:38 pm
Hi guys,

I recently acquired an early SG1000-II console; i read that D780C-1 chip is a Z80 clone; is it possible to have the pinout of that chip to extract audio to make a full composite mod ? Video was just "extracted" on PIN 36 (TMS9918A).

EDIT:
Audio out found on PIN7 of SN76489AN !
