Amiga 2000 PAL REV4.5 Battery & 1MB ChipRAM Upgrade
I have decided to upgrade my Amiga 2000 PAL REV 4.5 for get 1MB of chip ram. I also took advantage of this update to install a new battery for the system clock. Amiga 2000 PAL REV 4.5 Fat Agnus 8372A Installation:
- Install a new Fat Agnus 8372A or 8375 (8375 R1)
- Look for jumper J101 beside the power connector to the motherboard. Change it to the opposite position. (photo)
- Look for trace J500 at the back of the machine near the Cia’s (8520′s). It’s a jumper trace that you will have to cut with a razor blade. (photo)
- Look for trace J102 near the Fat Agnus (8372A). It’s a jumper trace that you will have to cut with a razor blade. (photo)
