The thing that bothers me the most here is that the meme is using 64bit assembly instructions, which did not exist at the time keyboards were using IRQs to communicate. 🤣

Did they upgrade PS/2 to use something other than interrupts? Because my earliest 64-bit CPU was in a computer manufactured in the early 00s and I'm pretty sure that mobo still had actual PS/2 ports, not USB converters or something.

PS/2 did still use interrupts.

And the first x86-64 processors were the AMD Opteron (servers) and the Athlon 64 (consumer-grade), both of which came out in 2003. PS/2 was still around then, so...

Meme checks out.

Here's a specific example of a Socket 754 (Athlon 64) mobo with PS/2 ports.

I stand corrected then, thank you! I forgot about Opteron and Athlon (I was an Intel devotee at the time, my AMD phase happened much earlier with the 486 DX2 and DX4).

Cheers!
