ocr: THE 8502 MICROPROCESSOR FOLD OUT SCHEMATIC SHEET 2, PAGE 74, FOR EASY REFERENCE. The 8502 is an HMOSII Technology microprocessor similar to the 6510/6502. It is the normal operating processor and is used in the C64 and the C128 modes. Fully software compatible with the 6510, hence the 6502, the 8502 also features a zero page port used in memory management and cassette implementations. The 8502 is also specified for operation at 2 MHz. The 2 MHz operation is made possible by removing the VIC from the system. The VIC chip is never completely removed from the C128 system, as it continues to funct ...
