I continue to upgrade my Amiga 2000 PAL REV 4.5. I have upgraded the Kick Rom and added my Vector A2000i zorro Card with 4MB of fast memory.

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)

Today i picked up a Commodore Amiga 2000 (Revision 4.5) in good working condition with Keyboard and Mouse.

I have removed the battery and thoroughly cleaned the PCB in that area. I noticed that the PCB is pretty delicate when trying to unsolder. The solder mask becomes damaged when exposed to too much heat for too long, and probably one would easily kill leads unless being extremely careful. Maybe the board’s age adds to it.

from Wikipedia:

The A2000, also known as the Commodore Amiga 2000, was released in 1986. Although aimed at the high-end market it was technically very similar to the A500, so similar in fact that the A2000B revision was outright based on the A500 design.

What the A2000 had over the A500 was a bigger case with room for five Zorro II proprietary expansion slots, two 16-bit and two 8-bit ISA slots, a CPU upgrade slot, a video slot, and a battery-backed clock.

It should also be noted that, like the Amiga 1000 and unlike the Amiga 500, the A2000 came in a desktop case with a separate keyboard. The case was more PC-like than the A1000 – taller to accommodate the expansion cards and lacking the space beneath for the keyboard.

The Amiga CD32, styled “CD³²“, was the first 32-bit CD-ROM based video game console released in western Europe and Canada. It was first announced at the Science Museum in London, United Kingdom on 16 July 1993, and was released in September of the same year.

The CD32 is based on Commodore’s Advanced Graphics Architecture chipset, and is of similar specification to the Amiga 1200 computer. Using 3rd-party devices, it is possible to upgrade the CD32 with keyboard, floppy drive, hard drive and mouse, turning it into a personal computer.

The Amiga 600, also known as the A600 (codenamed “June Bug” after a B-52′s song), was a home computer introduced at the CeBIT show in March 1992.

The A600 was the final model of the original A500-esque line based around the Motorola 68000 CPU and the ECS chipset. A notable aspect of the A600 was its small size. Lacking a numeric keypad, the A600 was 14″ long by 9.5″ deep by 3″ high and weighed approximately 6 pounds. AmigaOS 2.0 was included which was generally considered more user-friendly than AmigaOS 1.3.
