Sometimes I think that if it were the old days, I probably wouldn't have been able to program. I remember that these days we program on top of 64bit virtual addresses, but how did developers do it back then
16 bit programs used 16 bit addresses, generally speaking.
Even with 32bit systems where you’d want more than 4GB RAM, application software still had 32 bit addresses (and thus 4GB memory limit).
I think it was a lot more common for 8bit systems to allow for 16 bit addressing though.
It’s been a while though. So hopefully I’m not misremembering things.
Attention spans were longer.
