The Apple //e bank switches. The 8086 uses The original request was for a greater-than-32 bit address space, not some hack segmentation. Apparently, the requester wanted to spend his time programming, not hacking around compile and runtime errors re-partitioning his data. Anybody can put a map RAM on a micro to [apparently] extend its addressing. Hopefully, one or more of the suppliers will take a leadership role by providing a true larger addressing feature. (Hopefully 64 bits.) And auto-inc addressing and unaligned data! Oops sorry. :-) Stan
