Maximum upgrade for an Mk2 is 16mb until Patrick does his memory board. According to this post by Hugo, the chips for the mk2 probably aren't available anymore (although he said he had a bunch of them). I just PM'ed him to see if he could send one over before the meet. If anyone else knows of a source for them post here...I couldn't find one with a bbs search.

If he will send them, want me to ask him to throw one in for you too?
