Back in the day I dabbled in 6510 code, and up until today hadn’t even bothered to look at a chart of opcodes for any of its contemporaries. Today I learned that Z80 uses $00 for NOP.
Loth as I am to admit it, that actually makes sense. Maybe more sense than 65xx which acts more like a divide-by-zero has happened.
The rest of the opcode table was full of alien looking mnemonics though, and no undocumented single byte opcodes? Freaky, man.
But the point is that not even Z80 used $EA. If the someone was real they probably meant every 65xx processor.
And I was making a joke about the D&D spider goddess.
But the word is “loath,” which has an accepted alternate spelling of “loth”. “Lolth” is the Dungeons and Dragons spider goddess, commonly worshiped by Drow.
NOP is $EA, of course, and… um…
…sorry, I’m just a Commodore 64 scrub, I don’t know nothing about this high and mighty Intel 8086 nonsense.
[looking up]
…it’s 0x90 on IA-32? WHAT? Someone told me every processor used 0xEA because that was commonly agreed and readily apparent. …guess I was wrong
My daughter told me the other day, “I bet I could figure out a Commodore 64 if I had one.”
Good luck figuring out LOAD “*”,8,1 by yourself, kid.
With the ubiquity of C64 emulators, that’s easy enough to demonstrate by experiment

She meant she could figure it out just playing around with it, not reading a manual or asking around. I told her she’d have to read a manual.
Erm I might be showing my inexperience here.
Is there no equivalent to
man LOADin the commodore world? Or even justhelp?That thing had 16K of ROM. Every byte was sacred. Only manual was on paper.
Not that I remember.
I can’t tell if you’re joking and deliberately invoking the original comic above

Not sure if this is a riff on the joke or not.

*Lolth
What? This is system programming, not web development.

Oh Christ, I can’t believe I missed that.
Operating on low sleep and responding before coffee.
I shall flog myself now
I thought NOP was 0x90. Edit: oh I just read the rest of the comment.
