My 150 (a gift from a friend's wife) works OK when it works, (once in awhile, for no rhyme or reason, it'll refuse to work and chirp at me, play death chimes, and go off. I got as far as determining that it was somehow caused by the RAM card, but I still don't know why.)

I also learned that the adapter for the RAM is kind of rare (?), which is fun.

It's a nice (if not somewhat limited) machine when it works!

This hobby seems to require lots of patience, because things sometimes never seem to work quite right unless you're constantly fiddling with it.
