There is certainly a few of them out there... [aren't there?] Are there any manufacturers skeptical of the potential market that I could lean on? How difficult would it be to build? Is it something that requires a lot of additional logic or is it relatively simple? Help me put my mind at ease.

Dave, why doesn't Commodore release the information about the 2630 add-on memory board that you built (to show them it could be done)? Post it as a kit, and maybe someone will take it on the way the LUCAS/FRANCES setup was done. My 2500/30 is screaming "Please don't sell me man! All I need is another 16 megs!" :) -- * Scott Busse email: O O O_ _ ___ ..... * CIS 73040,2114 ||| /|\ /\ O/\_ / O )=| * scott_busse@mindlink.UUCP l | | |\ / \ /\ _\ * scott_busse@mindlink.bc.ca Live Long and Animate... \

It's basically just a generic 25MHz 68030 bus. You need a couple of extra signals, nothing that would phase anyone who's comfortable with the 68030 in the first place. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "This is my mistake.

I have spoken to a couple of guys who are designing just such a card and will be trying to license its production before long. Don Kennedy Vision Quest Systems

The A2630 daughterboard was enough to act as a proof of concept for the daughterboard mechanism, but it was hardly complete to the point where your average hardware hacker could sit down and build it from a set of plans. The one prototype worked, though slowed down from the original intent, and only 12MB out of 16MB worked, due mainly to noise problems. >* Scott Busse email: O O O_ _ ___ ..... -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "This is my mistake.
