Apple II

Hello group,I have a disk ii drive that I can’t set the speed on. I use the Apple dealer disk alignment aid software as I always do. If anyone’s not familiar with this program 0 is in the center representing 300rpm. Either side of the zero will represent positive or negative. It shows a -1500 (which I know is not near accurate). Turning the variable resistor it will jump to +1500. Then bounce back and forth between the two positive and negative extremes without touching the resistor.

Can anyone point me to a manual for Advanced Disk Utility and formatting IIgs hard drives?Thanks

I have an Apple IIgs, 6.0.1, cffa3000 acting as a starup HD in slot 1, a GGLabs A2SCSI card (clone of Apple II SCSI Card) in slot 7 and a SCSI Zip drive. At the moment, no 800k drive.

My plan was to intialize Zip disks with a 32 meg ProDOS partition (booting HD)  and a HFS partition on each. At the monemt the GS does not recognize the ZIP. If the disk is in on startup .. nothing. If I insert after the desktop appears, nothing.

Anyone have any idea how I might get the Zip recognozed by the GS and formated?

Thanks

I picked up this EMCO brand joystick a little while back in a lot of stuff, and can't find much information about it.  It's a dual Apple/IBM joystick, with a switch on the bottom.  Then there are 4 pegs that look like some kind of adjusters sticking out of the bottom.  They aren't for centering/trimming though, as those adjustments are on top of the stick.  The pots measure just shy of 1Meg across, which seems odd to me.  And the switch for Apple/IBM mode seems to switch in or out 2 resistors.  I didn't have time to trace everything out to see exactly what is going on.  The stick seems to w
