Hard Disks

<From: "Zane H. Healy" &lt;healyzh(a)ix.netcom.com&gt; <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 Funny most hard disks are winchester in base technology even if they are removable!... The osborne folks tended to make strange distinctions. <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? A common one was the CDC hawk drives at 10mb per pack. As they were often more expensive than the cpu they were on they were not frequently seen on the likes of apples and s100 systems. They were more often seen on Novas, PDP-8s, PDP-11s and other minis. The larger multiplatter drives were even to costly for the smaller minis and were seen at those sites that had the larger PDP11s or even bigger machines. Back in 1980 a Hawk (10meg) was something close to twice the price of a complete NorthStar* Horizion with two floppies, 64k and terminal. Two years later non removable drive would be quite cheap compared to that but removeable platter drives would still command a premium. Now a Zip drive compares to common IDE hard disks. Allison
