... pie izejas un ieejas bija mazs transformators brūnā epoksīda lējumā, kaut kur mētājas ...
... neatradu draiverus (win3.11 vai DOS) un tā arī neesmu notestējis!
Shēma no 51 TTL mikroshēmām! Shēmu nezīmēšu - bet ja kādam tā kautkur mētājas,
būšu tikai priecīgs šai blogā to pievienot.
Katra  TTL patērē no 100mW  līdz 250mW =
teorētiski kopā viss patērē no 5,1W līdz 13W - 5V ...2,6A.
