SemiOT: Mourning for Classic Computing

It's been long enough that I don't remember the exact causes, but in order to CALL/RETURN something you had to execute an inordinate number of instructions. I hated it. I liked the 8085 for real time stuff (good self-contained interrupt structure). The z80 for mixed lang programming. But the 6800 and up were plain elegant and easiest to code. A highly orthogonal instruction set. I am still somewhat of an expert in 68hc11 programming :-) . The 6502 and the X,Y pointer mechanism, though good for graphics, I never liked entirely... I could comment on something other than 8-bitters, such as DSPs or a couple 32bit uproc's, but that would be too long. -------------------------------------------------------------- Carlos E.
