Clock 3.579545MHz HM86171 - Hualon Microelectronics HMC HM86171 VGA 256 colour RAMDAC (DIP28) 6264 - UT6264PC-70LL 8k x8 SRAM (DIP28) * - QFP120 IC marked 55102602-12. Logo on the chip is of two 5 1/4 inch floppy discs standing upright and next to each other, with the corner facing up, like 2 pyramids. The middle hole and head access slot are visible too. Chip was manufactured 50th week of 1993 AR17961 - == Oki M6295 (QFP44). Clock = 1.500MHz [12/8]. pin 7 = high VSync - 60Hz HSync - 15.28kHz *********************************************************************************************************************/ #include
