-
- > 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.
