But, you are also limited by the speed of the motherboard RAM chips, no? So, if you buy an A3000-16 but want to run a (say) 25 MHz accelerator in the future, you should put 80ns parts on the motherboard, right? -- Stephen Walton, Dept. of Physics & Astronomy, Cal State Univ.

No. >So, if you buy an A3000-16 but want to run a (say) 25 MHz accelerator in >the future, you should put 80ns parts on the motherboard, right? You should do that anyway. The RAMSEY chip runs tighter cycles at 16MHz than 25MHz. Both take advantage of 80ns parts. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "This is my mistake.
