Yes, and that's precisely why the Apple 2 is still on my hobby / workbench. It's simple to interface with, and with a faster clock, remains useful.
And the Apple has slow RAM and fast RAM in a similar way. Really, to get the machine to run at 16Mhz, it's necessary to copy code into the fast RAM on board the card, leaving system RAM unused.
The Color Computer, Apple 2 and some others were made in a simpler way that did not interrupt the CPU for refresh and or video access cycles. That makes projects like this easier.
