Welcome Michael.
Any suggestions for next steps?
Assuming you've checked all the voltages across the entire board..... After voltages I start looking at clocks, and some basic chip signaling. Feel the chips for thermal issues is usually a good idea too. If the CPU is largely idle (check the CPU A0 or D0 pin) take a look at the reset pin on the CPU and trace that back. If I remember correctly (its been a while), you'll see a timer chip that is responsible for bringing the CPU out of reset and dealing with the out-of-reset on sequence after a minimum amount of time after power is applied. You'll want a scope for this, although you can broadly get away with a meter for basic work. Sounds to me like maybe the CPU is being held in reset. -- Steven Toth - Kernel Labs http://www.kernellabs.com
