Additional RAM

[hamtronix]

So does RAM beyond the 8MB limit have to be added via an accelerator or processor of some kind or is there a board (for the Amiga 2000) that can add additional RAM without going through the processor add on?

Currently I have 16 MB. 2 MB on A25000 card, 8 MB on GVP SCSI, 4 MB on A2630 Accelerator. But of course only 10 MB is being addressed. I have the 2 MB MegaChip.

Yes

No

Don't beat about the bush Piru, tell him straight  :lol:

Overloading the bus with RAM probably isn't such a good idea for stability/autoconfig purposes. I'd recommend getting rid of the 2052/25000 card and disabling or taking off a few MB from the GVP board. Plus, it'll free up a Zorro slot for some other fun board.

Actually I tried to give the card away here when I thought it was defective. But then I realized it was just being ignored. I just put it back in to keep it safe in my house. But when I get my new Denise chip I will yank it out. Thanks!

Actually there are methods to squeeze in a bit of extra RAM - but only small amounts, hardly worth it.
If you're running a 1 MB Agnus, there's a way to add up to 1.3 MB pseudo fast RAM, there are/were a couple of A500 boards around.
On an A2000 you could alternatively use the Ranger board from an A2000A model, (up to 1 MB) - I've been told that it also works in later A2000 models (1 MB chip required to avoid collision).

In general Piru's right - of course. With a 68000 or EC020 there's only 16 MB total memory space that can't be overcome. An accelerator's CPU expands that to 4 GB where there's plenty of space to add RAM, depending on the card/mobo.
