Had the Q605 board up and running in a P460 case, grooving along with 36MB of RAM and 512k VRAM, full 040 with a heat sink. I was getting ready to do the 33MHz hack. Everything was very happy.

Left it on over the weekend. When I got back the mouse was frozen, clock was frozen, Mac was frozen. I was busy so I just turned it off, and went about my day. Didn't give it much thought.

Came in today early with my new-in-box LCPDS Ethernet card (thanks olePigeon!), popped the case, seated the card, hit the switch, and got the regular startup chime followed immediately by the 8-note major-then-minor Chimes of Death.

So I went into test mode.

  • Without the new Ethernet card, COD (I left it off for the rest).
  • Without the 32MB RAM stick, COD.
  • Without the 2 VRAM sticks, COD.
  • Without the external Zip SCSI drive, COD.
  • Without internal SCSI HD, COD.
  • Without (brand new) PRAM battery, COD.
  • Without floppy drive, or any SCSI drives, or RAM, or VRAM, or PRAM battery, COD.
  • As above with a different power supply, COD.
  • As above with the original LC040 chip, COD.


Other than capacitors, I'm out of ideas. Anyone have a secret technique/test/idea before I spend even more money on this getting it re-capped (for no guarantee of working)?
