Appendix A: Hmmm, that didn't work

(troubleshooting).

Hopefully you had no problem getting the Apple II Pi working. But, if you did, here are a few things to

try:

• Did the Apple II turn on? Although the Raspberry Pi is a very low-power computer, there is a

chance it could overwhelm a fully loaded Apple II. Triple check that the Raspberry Pi is

plugged into the header correctly. Then, try removing everything except the Apple II Pi adapter

card and the floppy controller card. If is still doesn't turn on, try removing the Apple II Pi card.

If it does turn on, remove the Raspberry Pi from the adapter card and try the empty adapter

card. If it still doesn't turn on, the adapter card may be defective. Call your dealer. If the Apple

II won't boot with the Raspberry Pi properly connected, your power supply may be on the edge

and need replacing.

• Did the Pi turn on? Triple check that the Pi is properly connected to the header on the adapter

card. Is the SD card firmly connected? If it still doesn't turn on, remove it and try it with a wall

wart adapter that is known to work. Does it work with the wall wart adapter? If so, your Apple

II power supply may be on the edge and need replacement.

• Did the Pi turn on, but no video? Have you tried the monitor+cable+angle-adapter before with

the Pi? If it worked earlier, check all the connections when it's inserted into the Apple II. Some

DVI monitors need a boost setting that can be found in the /boot/config.txt file.

• Did both turn on, but no connection beep? Is the Apple II sitting there with a spinner icon in the

corner? This is probably because the Apple II client code is looking in the wrong slot for the

Apple II Pi adapter card. Press any key to exit the Apple II client and type run config to run

the Apple II Pi configuration program. Double check the slot assignment for the Apple II Pi

adapter card and enter the value. It will be saved. Type run startup to establish

communication with the Raspberry Pi. If this still doesn't work, you may have a defective

adapter card or Raspberry Pi. Call your dealer.

• Everything connects but the keyboard is erratic? Don't forget you are using a ~30 year old

keyboard. It may need some cleaning or use to remove oxidation from the key switches. There

are many resources on how to clean an Apple II keyboard, but pressing the troublesome key a

few hundred times might just clear it up.
