Amiga 2000-A

This is the original Amiga 2000 mainboard, designed by a team at Commodore in Germany in 1986.  It was no longer produced after the Amiga 2000-B board was designed and built.

It’s very different to the later revisions of the Amiga 2000 ain board, as it’s based upon the Amiga 1000.  It uses the same Agnus chip as the Amiga 1000, so it can only address a maximum of 512KB of Chip RAM.
