I killed a set of roms by inserting them the wrong way, they got very hot and didn't work again. Isn't pin 1 listed on the motherboard?
For your reference:
• Red - An error in the Kickstart rom as detected.
• Green - An error in the Chip Ram was detected.
• Blue - An error in the custom chip set was detected.
• Yellow - The CPU encountered an error before the system's error-trapping code (the code the calls up the Guru) was in place.
• Black - No CPU detected.
• Grey - CPU Passed the test.
• White - CPU failure.
