I got an old Classic II, however when powering up I hear the drive spinning, but no chime, just black with white junk all over it. Not sure what I might have to do to fix it. Any ideas?

Hello everybody, the title says it all.

I am looking to buy Shadowkeep if anyone knows someone selling it.

I have tried the various emulator versions, but all of them are ruined (someone played on the originals which makes it so you can't start over). So now I am just hoping to buy the disks themselves (and then a system to play it on, old-school style).

recently,I try to created IBM PC joystick converter to apple II,but I failed.because this document tell me.auto fire joystick ciruits's reason.it usually turn off this function.I look for google.auto-fire mean gamepad??right??I use gamepad and pinout.I guess ciruits.so I failed.someone can explain it??
