Quirks

• The motherboard is labeled Firepower Systems, Inc. instead of Motorola.
• When the system was first powered on, it booted enough to give a "no RAM" beep. Later attempts did not give a beep. There are four diagnostic LEDs on the board labeled A, B, C, D. When booting with RAM, light A stays on. When booting with no RAM, light C stays on. When booting with no processor card, no lights stay on. The beep no longer happens. Purple believes this may be due to the capacitors no longer being able to function properly and only managed to work for the initial power-on before becoming useless for further attempts.
