I have a problem with an Apple IIe I just bought. It does start with a usual "Apple ][" Screen, but when a floppy drive is attached the drive starts to run but it seems not to boot the System. I get some notes on the screen (see photo in my Forum) http://myoldmac.net/cgi-data/forum/phpBB2/viewtopic.php?p=794#794
During the boot process the first sector from the floppy is loaded into memory at address $801 and the code is executed. If your sector 1 happens not to contain a valid program, the CPU will soon hit an invalid instruction, usually at address $8xx, and beep and show you the monitor prompt with the offending address.
If all of your floppies behave this way, you may suspect the memory. You can use the monitor to test the memory. -Alex.
