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 (5 MACHs). I strive for 14 MACHs, and even for 21 MACHs.

Very nice! You manage to switch clock frequencies on the fly with no disturbance to the system?

Here's the movie you linked - it didn't quite work for me through the translator:

Yes, the translator is messing up something...

That looks great! A 6502 system accelerated to 5MHz using a 65C802, and switching clock speed on the fly. Very nice job.

(The link as supplied by BigEd worked fine).
