I fear that I may have killed my apple IIe by plugging an IBM 5151 cga monitor into the game/joystick port. It no longer beeps, and the power led stays on. No video output. As to how this happened, I have an Apple IIe with a PC Transporter card from Applied Engineering. I plugged the monitor into the wrong port.
I've taken all of my expansion cards out, and measured resistance on all of the voltage rails to ground. The 12v rail had very low resistance (6.5 ohms), but raised to over 800 when I unpluged the keyboard.
I would really like to get this IIe working again, it has a few AE upgrades and is fairly unique. Any help on what could be wrong is appreciated!
