My trick for making a Mac opening tool:
Take a BIC disposable pen, and remove the ink and the black end piece,
leaving an empty tube. Shove a hex shaped pencil in one end, and a T-15
driver bit in the other. This creates a crude, but very functional Mac
opener. This works best if you use a new pencil, and only partially
sharpen the end to make it easier to wedge into the pen barrel. It's
actually pretty easy to use. There are five screws in the back of the
case. The two you need the long screwdriver for are way down in the
handle. There are also two near the bottom, above the ports, and one
hiding behind the battery cover.
And here is a page describing the sad mac error codes.
http://www.mac512.com/sadmac.htm It looks like your problem is a bad
RAM chip. My 128k had a bad RAM chip too. I unsoldered the old chip,
replaced it with a socket and stuck in another from my junk box. I
think (but I don't remember for sure) that it came from a junked XT
motherboard. (Either that or a broken TRS-80 Color Computer).
Good luck!
