I had to take apart the original power supply of my Apple IIe to get it repaired, in the meantime I had to power my Apple IIe by taking the right supply voltages from an atx power supply which apparently works well. I plugged in and turned on my Apple IIe.The computer appears to be coming on, but a white screen appears on the screen which then disappears and is alternate with a black screen with white horizontal stripes, as if doing a test. What is the problem?
Thanks

Disconnect the keyboard or hold both open-apple and closed-apple keys while turning on. That should ru the self test.
I solved the problem by disconnecting and reconnecting the keyboard, it probably wasn't connected well. Now it works regularly.
Thank you very much
