How to increase Chip Ram ?
« on: February 22, 2012, 02:04:00 PM »
My A2000 has 512K Chip ram and 8MB fast ram.

How can i increase the chip ram to say 1MB ? I need 1MB cause a lot of WhdLoad games need it.

The motherboard is Rev4 and according to WhichAmiga by Piru, the Agnus is OCS PAL Agnus 8367.

If it helps the Graphics system is Amiga ECS and the graphics chip is ECS Denise 8373.

If it helps, mine has the Mono Video jack at the back. I heard that if they have this then it is not the earliest A2000 based on the A1000 and 1MB chip should be possible.

Done! I replaced the Agnus to an 8372, opened J102 and J500 and put J101 in the other position.

I now have a ECS 1MB Agnus, PAL display (J102) and 1MB Chip ram.

The board is a rev4.4 . I never even knew i had the extra 512K fast ram (which is now addressed as chipram)
