The power LED should start dim and then go bright about 1 second afterwards. I've never heard of a scenario where it starts and stays bright. Only the other way around (starts and stays dim). Do you have an EPROM burner? DiagROM is open source and freely downloaded here
. All you need to do is program it onto the proper eprom, an AM27C400 and put it into the kickstart socket.
Also, what happens if, after turning it on, you repeatedly hit the CAPS LOCK KEY, turning it on and off , say 20-30 times? Does the LED ever get stuck to the ON position on the caps lock key, or, can you continuously turn it on and off by repeatedly pressing the caps lock after numerous presses?
