I recently acquired a fully working Macintosh SE. It has a 20mb hard drive, and it is the model that can only read 800k floppies. It currently has 1mb of ram, but i really want to upgrade it to the full 4mb. The only problem is I have never done a ram upgrade with this old of a mac before. I have only done ram upgrades in iMac g3 and Powermac g4s. So i was wondering if you guys think I would be able to do the upgrade myself without breaking my mac? I also have a couple more questions: Is there anything I should be careful of when performing the upgrade? I know the ram needs to be a special type, so could you link an ebay auction or another site with compatible ram? And finally, is there a guide you recommend (preferably with pictures) that would show me how to replace the ram. Thanks in advance for any help/advice you can offer.
