If they had done that, it would have been (more) possible to extend the address space without totally losing backwards compatibility. Or if (...) (25 years ago, 20-Jul-99, to lugnet.off-topic.geek)

(...) Wait a minute. Feel free to correct me if I'm wrong, but the segmented memory architecture allowed you to create absolutely *tiny* programs that did wonderful things.

(...) Well, I've been running Emacs on a P150 system with 643MB harddisk for three years now. That's smaller than a CD, right? Or were you refering to transporting the Emacs sources on a CD?

(...) Relative pointers in the same segment take up half as much space as a 32 bit pointer. Depending on what you're doing, the savings here can be considerable. .COM programs used nothing but relative pointers and fit in less than 1 64K segment. (...)

(...) OK, relative-addressing mode is good. But it doesn't require segmented memory. All it requires is an instruction format with a defined result. For example, the conditional-jump instructions on the 6502 microprocessor[1] only used relative (...) (25 years ago, 22-Jul-99, to lugnet.off-topic.geek)

(...) Perhaps you're right, but that jump instruction is relative to the Instruction Pointer which uses a full register. The segmented way you are relative to a segment which only uses half a register. You can take advantage of this half register (...) (25 years ago, 22-Jul-99, to lugnet.off-topic.geek)
