Re: Lisa keeps shutting itself off

1) I do not have a fully-working copy of MacWorks Plus on floppies yet. I bought a set from VintageMicro, but the boot disk failed to work, so he's sending a replacement set.
2) The only times it has shut itself off was while sending data to the printer, correct. Prior to the last occurrence, I had the Lisa running for well over an hour without doing any printing, and it printed fine for at least a half-hour before shutting itself off.
3) That is a good idea. I will connect my ImageWriter II to Serial I and try printing said document a few times, to see what happens.
