Good day.
AGAT-9 is not AppleII-clone, but AppleII-like Soviet computer.
I want to introduce to You the turbocharged version of this computer : CPU is W65C802, dual-port static memory (any piece of the main 128 KB of memory can be used as a text or graphic video page), currently accelerated 5 times ...

I myself was thinking about using a dual-port RAM with Ben's design, but these are not only hard to find but also either too small (2K) or too expensive... Good for text, but not so for graphics...
What do You think about it: IDT7028L15PF8 , 5V, 64Kx16, 15 ns, TQFP100, price $3.13, shipping cost ...

May be something from it could be useful for You.

In October, 2014 I have bought W65C802P-6 from digchip.hk . The chip was cost $10, and the delivery to Russia was cost $10. Successfully works at the increased frequency in the AGAT ( Russian Apple][Plus-compatible computer ). Further acceleration is still in process.
