Apple IIgs 3.5 Floppy problem

[Apple IIgs 3.5 Floppy problem]

I repaired two drives with the same problem. The price is for 4 cogs but I received 6. The plate layout is probably configured for 6 to yield 4 after inspection. Anyway, they work like a charm.

EDIT: I missed the second part of your question. Yes, you will have to manually eject if your gear will not engage.

[AST Multi I/O card]

Please check at Apple II hardcore web site there instead of this forum.

 

 

You wouldn't have a link to that hardcore Apple II website by any chance? I have posted this request on a number of retro-computings forums. The Apple II Documentation Preservation Project has not archived the manual. Any lead is appreciated.

[AST Multi I/O card]

I'm trying to track down a user's manual for the AST Multi I/O card. It is supposed to provide parallel and serial ports, as well as a system clock for the Apple II. I managed to locate a utilities disk image for the card on Asimov but I have been unable to find any written documentation. It has a series of jumpers and DIP switches that, without some functional understanding, are useless. Any help is appreciated.
