I have just recently inherited an Apple II+ Plus from my late godfather. I got it working with little trouble, but then the power supply blew up. I bought a replacement for it from ReativeMicro and just installed it. Since installation I seem to be having trouble with getting the Apple II to read disks. Now when turning on the Apple II, it flashes the screen with random characters for a split second and then just stays at the Apple II screen with the drive spinning, I can get it to boot to BASIC by pressing CTRL+RESET.
I have a feeling it is either a problem with the Apple II board itself or the Disk II interface card. I have tried to swap between the two disk units I have and whatever I have connected to the Disk 1 slot is what is endlessly spinning.
Any help is greatly appreciated!!
