> How can i, in a basic 2000, augment my chip memory ?
There are two different answers, depending on how "basic" your 2000 is.
If you have the original "Fat Agnus", which only supports 512KB of "Chip
RAM", you can easily replace it with the "Fatter Agnus" (1MB Chip RAM).
This revision will require you to make two minor "jumper" changes on your
Rev 4 or later motherboard. The other 512KB of Chip RAM will come from what
you now see as "Fast RAM".
If you want to install the 2MB "Super Agnus", you will need the special
conversion kit that comes from a third party supplier. It is a daughter
board that plugs into the Fat Agnus slot (and connects with logic probes to
a couple of other chips) and includes the second MB of Chip RAM onboard.
> Am i obliged to buy a graphic card to put memory in ?
No. Unlike video RAM on various graphic cards, Chip RAM is fully visible to
the Amiga's CPU. Once you have enough Chip RAM, you may discover that you
need more "Fast RAM" in order to take full advantage of AmigaDOS' preemptive
multitasking.

In order to increase the amount of chip ram, you need the DKB MEgaChip board, which will give you 2M of it total, adding onto the 1M already there. You can get a graphics card, but some seem to need chip ram available, if only for the OS to feel there is enough ram available, even though the actual data is in the gfx card's memory instead of chip. Find a card you like and ask around to see if you would still need the megachip anyway. I have one in my A2000 now, and wouldn't be without it anymore... Bill

Get a DKB MegaChip 2000 and you will have 2 megs Chip RAM. They work great. If
you already have 1 meg Chip then it is a plug in replacement. If you only have
512K Chip it will take a modification/jumper change on the mother board
depending on the MB revision.

The only easy way to add more CHIP RAM to the A500/2000 is
to buy the MegACHIP 2000 board made by DKB. This comes with
the Fatter Agnus chip and an extra 1 Mb of RAM onboard to
augment the 1 Mb of memory on the motherboard of the A2000.
I wrote a review of this product for Amiga Report magazine.
It is in issue 306.

Am i obliged to buy a graphic card to put memory in ? The DKB mega-chip replaces your agnus chip & gives you 2 meg of CHIP memory.It does this by pulling in any available fast ram on the system. Many Scsi cards accept memory & there are still stocks of memory only expansion cards/or accelerators around in the 2nd hand market.These however only allow the expansion of FAST ram. -- M Read

You put a 2 meg agnus in the top (that you can puchase with the board) and attach two clips to the motherboard, and you've suddenly got two megs of chip ram. I've been using ine here for a few years. Not to be attempted if your a scaredy cat when it comes to taking your Amiga to pieces. -- John - Marina Sirtis found face-down in saucepan full of cheesecake - Paddy Ashdown spotted leaving the scene.

It works great, but I use don't use it anymore since I have an A3000 too. ______________________________________ / \ ( Evert vosev@sh.bel.alcatel.be ) \______________________________________/

Just buy the MegACHIP 2000 board from DKB. It costs about
US$195. If you already have 1 Mb of CHIP RAM then you won't
have to do any hacking at the motherboard; otherwise, you'll
have to make a cut and move a jumper depending on revision.
