THE DELAY CIRCUIT IS NEEDED IN ORDER TO "SHIFT" THE GENERATED\nCLOCK FORWARD ENOUGH TO MAKE SURE THAT READS/WRITES DURING\nDOUBLE CLOCK PERIODS HAPPEN WITH /CS LOW AND CLOCK HIGH, AS\nREQUIRED BY THE SID DATASHEET.\n\nWE ALSO GENERATE AN ACTIVE-HIGH RESET SIGNAL THROUGH THE GAL\nIN ORDER TO LET THE CD4520 ALWAYS BE IN A KNOWN CONDITION AT\nPOWER-ON/RESET.\n\nTHESE TWO THINGS DO NOT SEEM TO BE REQUIRED BY THE OLDER\n4520'S (THE SAME ONES THAT SOLDER HIMSELF USED ON THE CARDS\nHE BUILT), IN THIS CASE JUST SHORT R11 AND DO NOT MOUNT C20, THE\nRESET SHOULD NOT HURT ANYWAY.\n\nSEE https://plus4world.powweb.com/forum/45294 FOR MORE DETAILS
