A PDQ with RAM maxed out does take a long time to boot. Enough to make you think it's broken the first couple of times. However, with 512K you can reasonably run Tiger on it if you are so inclined. I did for several years. Now I've retired mine to OS 9 translator service, as a handy machine to access SCSI, serial, LocalTalk, floppies, ADB and other old school technologies that the Cube doesn't support.
