"emphasis on that an old computer or console could produce (this is the original meaning of the term)"

Yes, old computers and consoles with sampling capabilities. Chiptune means to "emulate" older sound chips with sampling hardware.

In the nineties SID music was just SIDs.

"For example the intro of "Cannon Fodder"[1] on the Amiga is not considered a chiptune, because it used samples from real instruments and a human singer"

Agreed.

"For some original true chiptune, see the amazing work of the amazing Rob Hubbard[2]"

Rob's work is amazing, but I really don't think he'd refer them as chiptunes.

In the early nineties, as a demo (intro) coder you wanted a chiptune when you had space constraints. 40 kB total for code / gfx / music, which was a pretty common size limit for Amiga intros that time, so you had maybe 4-15 kB for the chiptune.

How do I know? I was there.

I was there too.

Not disagreeing with what you wrote, I was replying to "Absolutely no one referred to SID, YM etc. tunes as chiptunes in the *nineties*"

They absolutely did in the 90s.

I was organizing chiptunes nights in my city in Italy in the late 90s early 2000s and we were calling it either 8bit music, chip music or chiptunes.

I did not invent the format, I discovered it in Berlin at the times.

The guys in Berlin told me that they imported it from Tokyo ¯\_(ツ)_/¯

His Commando tune is pure gold, I still love it after about 40 years since the 1st listen. A real song that I plan to make a rock cover one day, hopefully before I die (did I say I'm quite lazy?:) Others already did metal covers, sometimes with good results [0]. My idea is to keep it funky like the original and use mostly real instruments.
