more RAM , how?

[Piru]

If you wanted more chipmem, you would have to replace the custom chips with new versions which supported more RAM.

It should perhaps also be pointed out that there is no such custom chips available. 2MB is the chip memory limitation in hardware. WinUAE can have upto 8MB "chip" memory, though.

Oh my peg2 has 1GB of memory ;-)

Of course :-)

Yes but then you have to use Windows  :-P  :-P  :-P  :-P  :-P

with an expansion card!
it's only mode to have 10 mb on Amiga

I try to expand for octamed to use longer samples.

I believe the newer versions of octamed also use fast memory instead of chip, so you should really upgrade your software  :-)

[kd7ota]

I have used both OctaMED v4 and Soundstudio.  Soundstudio usually pops up a message if you want to load samples into fastram instead...Well, I could have sworn it did. Its been 4 years since I last used it, but I do remember that message.

v4 Automadically used your fastram first before it tipped over to the chip ram.

Either way, it should be able to do much more then that.  :-D

That's not true, you could always use BANK SWITCHING  :crazy:

[InTheSand]

I'm quite happy with my bank!  :-D

Actually, if you were to have hardware-controlled banks of 2Mb ChipRAM, you'd need some additional software to control all of this - to do things like copying the screen's contents between banks, etc, before switching... Sounds nasty!

As if the original thought of replacing the 680x0 by a PPC doesn't sound nasty. I remember my original thought when I read the news about a possible PPC card for the amiga...

Tomas,

Upgrading Octamed?

How?
(I have only a demo version of OctaMed 6)

-I do not visit meetings anymore.

-In my area there is no one I know with an Amiga 1200, who also have Octamed in a higher version.

any suggestions?
Downloading from the internet and transfering to my miggy is still hard to do, because using a convert-prog is difficult for me. My (technical) english is not that good.

Hi Seiya,

Which expansion card is available?
Do you know any price, brand or type?

I can look for that!

If I understand correctly, this is basically a paging file? So the custom chips fill up the 2MB physical RAM chips, then when they require more memory some pages of RAM are moved to a file, thus freeing up chip RAM. Is this right? Could the memory pages be swapped in to fast RAM instead to make it faster? Presumably the ROM would have to be patched to make use of the page swapping rather than just refusing to run the application when no physical chip RAM is available.

Is any of this actually possible?

The contents of the chips aren't moved to a file, but the chips are instantly replaced with other chips standing by. Another memory map. This is what the old C64 did also.

So the custom chips would access the chip-mem as if they were never replaced, but in fact they are...

if this is possible is something else though

[motorollin]

Interesting. So there would be hardware in between the custom chips and the memory which can tell when the first bank of 2MB chips is full, then automatically switches to the second bank?

If the custom chips are addressing the same memory range no matter what bank was being used, how would the controller know which bank the required page is on?

The controller/library would perhaps sit inbetween the allocmem function and store additional information required somewere that can tell the memory map being used in the allocated memory block. The controller would need to monitor the address lines and the chip accessing the memory ? And than quickly switch memory map if desired....

although I feel something is missing

Perhaps you could say,.. Paula has map one, and Denise map two giving them both 2 MB each ?

That would seem to be cleaner. Is it only Paula and Denise who address chipmem?
