   Booting a PowerWave 604|132.   
   28 Dec 24 21:41:21   
   
   Hi,   
      
   I have a Macintosh clone PowerWave 604|132.  The user's manual is   
   available from the Internet Archive and other servers.   
      
   The power button on the front panel and the button on the keyboard   
   both cause the fan in the power supply to spin and the LED in the   
   front to illuminate. The display remains black.   
      
   I've tried two monitors and a second PCI video card.  The display   
   remains black in all cases.   
      
   Neither the programmer's interrupt button nor reset button has   
   effect.  Meaning the Apple ROM  isn't working?  The CPU isn't working?   
      
   Should an audible tone come from the speaker when the machine   
   starts?   
      
   One memory card is in each of two banks of sockets.  Removing either   
   card yields no change.   
      
   The clock battery is probably dead but shouldn't cause this   
   behaviour; correct?   
      
   Adjacent to the memory are ROM and cache SSIMMs in sockets.   
   Reseating is worth trying but the cards are stuck hard in the sockets.   
      
   Other ideas?  Poke around with an oscilloscope?   
      
   Thanks,                  ... P.
