Woot! Some serious progress. In no particular order: - Non-functional keyboard was traced to a (surprise) badly corroded stereo phone jack. What threw me was that plugging in a straight Switchcraft plug for continuity checking showed everything ending up where it should. After I took off the side of the unit, I discovered that the right-angle molded plug on the keyboard cable does not get inserted far enough to make a reliable connection. This looks iffy even at best, but I'll start by replacing the jack. By removing the daughterboard that carries it and plugging the keyboard into it directly, the computer sees it. That's the good news. The bad news is that (also surprise!) there are a lot of dead keys. So perhaps I spoke too soon about it being intact. I have a Sun 4 keyboard on the way and will pick that for parts to get going quickly. - Non-functional diskette drive was pilot error, but I don't think it was on my part. There are two 20-pin ribbon cables leading into the drive cage and the wrong one was plugged into the Lisa Lite controller board. Hopefully that did not damage anything - it was like that when I opened the unit! Plugged the correct cable in and it now tries to boot the floppy. I inserted the Lisa Test 3.0 disk 1 and it chugs away for a bit before throwing a disk read error. Will try writing another copy on my mac, since this one may have been damaged while working on the loading mechanism. I'm very surprised that so much appears operational given the horrible state it arrived in. A testament to Apple's construction quality, for sure. Steve --
