Re: Apple IIc Hard Drive??

[tmmadden@engin.umich.edu (Thomas M. Madden)]

That would be the QC-20 by Quark Periphreals, amongst others. I still 
have one of those things connected up to my old Mac 128K (which was 
upgraded to a 512K, which was upgraded to a Plus :-) ). It still works 
with the Mac great. Awhile ago, I tried to connect it to my IIgs, only to 
find that I had lost the Apple II driver floppy a long time ago. It's 
about the size of a VCR and actually has a rocker switch on the back that 
can switch it's firmware between Apple II and Mac. The only problem is 
that it didn't work like a normal hard drive. You still had to boot your 
Apple II or Mac with a floppy startup disk. As soon as the floppy loaded 
the drive's driver into memory, the Quark would take over and continue 
the boot process. This made it completly incompatible with GS/OS (I 
believe) and made using ProDOS on it difficult (I'm not sure about this- 
I just remember reading about it in InCider/A+ awhile ago). I did take 
it apart awhile ago just to see how it worked. It seemed to have what 
looked like a 5.25" half-height RLL drive mechanism in it.
