If any of these folks are modifying the design to work as an A2000 CPU slot
device, and need any help with the coprocessor slot protocol, let me know
and I'll try to help out.

A good portion of the 68020 boards sold so far are for this purpose.  They
ALWAY speed up rendering, but depending on the board design, the 32 bit
memory available, and the hard disk controller, they can actually slow 
down some other things.

And the A1000 is really only a hardware orphan.  I like the idea of PD
hardware, and may have some available for the 1000 sometime soon.

And the current ones are.  However, the LUCAS board is clocked faster than
any of the commercially available boards.  No one has yet marketed an
asynchronous design, though I've heard rumors of at least three of them
in the works.

Is there a 32 bit wide RAM design out for this yet?  Just wondering; the
7.16MHz RAM boards for the A2000 are pretty much slam-dunk designs using
standard DRAMs.  Faster DRAM boards require lots more thought, and I'd
be interested to see if anyone has it yet.
