That's my list exactly. What a trip down 40 years of programming! * 6502 in my Vic20 and Apple ][, as a teenager (both computers' manuals had complete circuit schematics) * Z80 assembly during my Elec Eng degree * 8051 assembly for embedded systems I built for some consulting clients during my PhD * DSPs including DSP32C (1992) and TMS320Cxx, considered for radar processing during my PhD (though by that stage, the 486 turned out to be good enough!) * x86 for everything else. Especially once PCs came with the x87 floating point processors (for 386, before the 486 integrated the FPU into the CPU).

Oh, the nostalgia! I remember the first "holy war" I was ever exposed to was Z80 vs 6502.

  I had a Z80 CP/M card in my 6502 computer (Apple ][) but my heart was always on the 6502 side.

  My first exposure to the Z80 was via Rodnay Zaks's book [1]. And, just because I was curious, here's the Vic-20's 6502 circuit diagram [2] [1] https://archive.org/details/Programming_the_Z-80_2nd_Edition_1980_Rodnay_Zaks/mode/2up https://archive.org/details/Programming_the_Z-80_2nd_Edition...

Fun fact - my mobile phone number ends "6502" :)

    The Vic 20 was the first commercial microcomputer I owned, and I did a lot of machine language programming on it. But the first microcomputer I owned was one I built myself, based on the 8085A (which was basically the same as an 8080). Since the Z80 was essentially an enhanced 8080, I could never choose a side on the Z80/6502 wars and consider the debate a bit stupid (like all holy wars).

I forgot about DSP32C, we had that in one of our vision systems. Fun chip but I preferred the TI offerings.
