Not sure why it was listed as '82, but if it was the C64, it makes sense. It's the most sold personal computer ever.

Nuance around this fact would be completely lost in 100 years, let alone 1000 from now.

I’d probably put 1978, but it doesn’t really make much difference if you say it was the TRS-80, Apple II or the c64. The thing happened about then.
