Hi,
Last weekend I was lucky enough to find a pallet of Apple II stuff (2
complete systems, and lots of cool things), and amongst everything was a
copy of a book called the "Apple II User's Guide" published back in '81 by
Osbourne/McGraw-Hill.
In this book under the chapter on Drives I found that it talks about three
types of disks; Hard Disks, Winchester Disks, and Diskettes. It also has a
picture for each, and it's the picture of the "Hard Disk System" that
interests me. It appears to be a Rack Mounted enclosure for a Removable
Disk pack. I can't see how many platters the pack has (the cover is white
plastic), but I would guess between 2 and 4. It has four square push
buttons (looks like the kind that light up), and two small lights.
Basically it looks like a "Micro" version of the disk packs I used to use
on Honeywell and UNISYS Mainframes. The photo was courtesy of "Cameo
Electronics", and I can see their logo on part of the case.
The text says the disks cost about $150 each and the drives between
$3000-10000. All in all a very fascinating looking peice of hardware!
I've never seen anything like them other than on mainframes, were these
very common?
