I recently picked up a powermac G3 B+W at a local junk shop, sans any memory or hard disks. When i plug it in and attempt to see if it will boot period, the PSU turns on, the front LED turns on, and i get one low beep(sounds melodic, not like a random bad signal is being sent to the speaker) but the monitor does not turn on at all. any ideas, or do you think i can't save this one?
