It's been awhile since I messed wtih older (well, older than my 1200) hardware - if a system comes with 512K chip, it probably has the original Agnus and there is no way to upgrade this to 1MB chip unless Agnus is replaced? If I dropped a memory expansion in the trapdoor, it would give me 1MB, 512K Chip + 512K Fast? How many games require 1MB Chip? The reason why I'm asking all this, is because I wouldn't mind picking up a 500 sometime just to hook up to play games instead of spending my days trying to get them to work on my A1200.
