It is my understanding that the 32 bit memory for the 2630 is rather slow
as far as 32 bit memory goes – something like 100 ns, which causes more
wait states. By changing the chips from 100ns to 70 ns 32 bit memory the
performance increases dramatically. (I get my information from a tech for
an Amiga dealer who also happens to own the GVP 3001 board, so he is quite
familiar with the subject.) What I want to know is why none of these boards
can be expanded beyond 8 megs when the 68030 can address so much more?
The 2630 has no easy way to speed up the memory. The 2620 had a jumper
you could change to speed it up, with a corresponding change in the memory
chips themselves to 80 ns parts.
The 2630 can be expanded via a daughterboard.
I don't know about the GVP A3001 card, but the Hurricane 2800 is set up to
go to a max 16 meg if you use 1Mx4 rams instead of 256Kx4. A jumper (at
least one, maybe more) has to be changed also.
