INTRODUCTION The C64 can only work properly with stable clocking. In a C64 II the MOS 8701 IC generates two major clocks and maintains the fixed frequency and phase relationship. COLOR_CLK is the main crystal oscillator clock and DOT_CLOCK is derived thereof. This blog presents a replacement circuit for the MOS 8701 IC. Orginal MOS… Read more C64 MOS 8701 Replacement
