First, congrats on getting a cassette tape setup working-- it's not quite as easy as the Apple II manual claims. On most 8-bit Apple II's, the Disk II drive will grind and spin if no bootable diskette is present (until you do a Reset). If you have not tried booting more than one diskette, the problem could be with the diskette you tried and the drive may be fine. If the problem is with the drive, the most common maintenance needs are ... o- Cleaning: The drive R/W head (which contacts the bottom side of an inserted diskette) is gunked up and needs cleaning. A 5.25" 'Head Cleaner Kit' from places like Radio Shack will include a Cleaner Diskette plus some Cleaner Fluid (mainly isopropyl alcohol). You open the bottom panel on the Cleaner Diskette, squirt some fluid onto the paper disk, and stick it into the drive (with the open panel facing down). Then you get the dive spinning-- like, you could just turn ON the Apple II and let it try to boot the diskette. Let it spin for about 20 seconds. o- Speed: The Disk II occasionally needs to have its speed adjusted. You can check Speed by booting Copy II Plus and selecting VERIFY-- SPEED. (Be sure to stick in some blank or 'don't care' diskette for the speed check as directed by the program.) If you do not have Copy II Plus (or some other program which checks speed) or if nothing boots, you can check speed by removing the drive cover and bottom, flipping the drive, and viewing the strobe pattern on the drive pulley under a fluorescent light. If the pattern which corresponds to your power line frequency (probably 60Hz) is stable, the drive is on-speed. If it looks like your drive is off-speed, you can use a mini-screwdriver to turn the speed adjustment screw. The thing you need to adjust is located on the little rear-mounted board at the right rear side of the drive. There are a few other things to try; but, the two above are, by far, the most frequently needed fixes. See the newsgroup Floppy Drive FAQs at http://home.swbell.net/rubywand/Csa2FDRIVE.html for more about Apple II disk drives. Since your Apple is a IIe, it is very likely that you have the right Disk Controller card (i.e. the one for 16-sector diskettes). If you want to check the card, see the info supplied by Neal Parker in the FAQs at http://home.swbell.net/rubywand/Csa2FDRIVE.html#017 . (Be sure the Apple II is turned OFF when you unplug the board.) In case you need some getting started software (e.g. bootable DOS 3.3 and ProDOS diskettes with a few useful programs) you can email some regular poster to this newsgroup. Cost will usually be $5-$10 (i.e. enough to cover mailing and materials). Rubywand
