Thanks for your answer! The daughter card has been reseated when I plugged the memory card in. Is there enough room for a spacer between the two? It looked pretty packed in there! And what kind of spacer are you referring to?

By the way, I'm posting this reply from said PowerBook, in Netscape 3.1, surfing the web through LocalTalk Bridge running on my PB1400c. So cool! Today I only had to pull the plug once for the 145B to boot fine...
