Disk Drives

[Lyle Bickley]

I was a FE on the IBM 7094 in 1963 and 1964.  At that time Lockheed (Mountain 
View) had an IBM 1301 Disk (56 MB, Moving Head Disk, 156K char/sec) and an 
IBM 2320 Drum (830K char/sec) attached to an IBM 7631 Controller connected to 
an IBM 7909 Data Channel.

For the 1301 take a look at:

As you can see, the disks were huge!!!
