There is another way to add 2MB to an A2000.  In principle, you'd be in essence duplicating the megachip or similar.  The hardware hack involves piggybacking ram chips on top of others, rewiring, cutting traces, etc. and adding a 2MB Agnus.  There are instructions on Aminet, usenet, etc.  afaik it only works on Rev 6 A2000s which have the larger capacity dip ram chips already on the board.  Same applies to Rev 6 A500 motherboards as well.

again, this is not for the faint of heart...but it's a fun experiment and since another A2000 m/b on ebay is cheaper than a single megachip, you risk little if it doesn't work.
