| | The 6502 Instruction Set Decoded |
 | | The bit manipulation instructions found only on the Rockwell and WDC versions of the 65C02 are not included in the table, nor are the "undocumented" instructions of the original 6502. | | | Similarly, the test-and-branch instructions are of the form xyyy1111, where x is 0 to test whether the bit is 0, or 1 to test whether it is 1, and yyy is which bit to test. | | | The new instructions of the 65C02 are much less logical than those listed above. |

| | There may indeed be bugs, especially in the 65c02 emulator part, since I have not tested it exhaustively, but all this has reached the stage where I thought that someone else might find it interesting. | | | DS xxxx - define xxx bytes of storage (filled with zero) STR "string" - define a length-byte string in memory ASC "string" - define a null terminated string in memory. | | | #ADDRESS for low and high bytes, respectively.) The 65c02 emulator includes a 65c02 instruction execution unit and a simple monitor that allows you to see and edit memory, step and trace, see registers, change banks of memory, load object files produced by the above assembler, and begin execution at an arbitrary address. |

| | The three major changes were the internalization of the powersupply (previously an external brick-on-a-rope as users liked to call it), a built-in 800 kB 3.5 floppy drive replacing the older 5.25, and finally, the equivalent of a ZipChip 4 MHz accelerator built-in. | | | It had 128 kB RAM, (expandable to 1 MB) a built-in 5.25" floppy drive on the side, and could be used with a mouse. | | | Apple licensed the add-on technology from Zip Technologies to incorporate the accelerator as standard in the IIc+, though in doing so, broke it out into an ASIC, SRAM and a faster 65C02 (the ZipChip had all that intergrated into a tall 40-pin DIP chip). |
