Even dual ported video memory did not solve this problem entirely. There still had to be a hardware mutual exclusion logic to prevent conflicts. Some graphics chips, like the Motorola MC6847 were so nice to have a signal that tells when it's accessing video RAM and when it's not. That practically was all you needed for mutual exclusion. Letting a graphics chip trigger an interrupt upon entering the vertical blank was another option. This would automatically also eliminate the problem of any other interrupts since you already were in an interrupt routine.

But, of course, that also opens another can of worms anywhere where nested interrupts are allowed or things like non maskable interrupts are a thing.
I have lived with several Zen masters - all of them were cats.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
