>not only did the address wrap around to 0, ... Very reminisce of the 6502 "issue" of jumping with an address on a page boundary. Per Wikipedia: the processor will not jump to the address stored in xxFF and xxFF+1 as expected, but rather the one defined by xxFF and xx00 (for example, JMP ($10FF) would jump to the address stored in 10FF and 1000, instead of the one stored in 10FF and 1100). This defect continued through the entire NMOS line, but was corrected in the CMOS derivatives. |
