Re: IIGS Acceleration Idea

So much of the custom logic on the GS is designed to run at the
vicinity of the 2.6mhz speed.  Now what speed the logic can handle is
an unknown, probably not 10mhz, but possibly somewhere in the range of
3.5mhz - 5.2mhz.  Ram would have to be upgraded for sure, but 50ns DRAM
are obtainable.  A 5.2mhz (double 2.8mhz) cachless accelerator mod for
the masses wouln't be a bad idea.  This is assuming we can trick the
VGC into stepping down the appropriate amount to synch with the stock
1.023mhz for "slow I/O", video, etc.

And I think the 3.5" drive handling depends on the 2.8 MHz speed. If this is so, you'd need at least three speeds to handle it all.
