Early on the hub specs tended to vary. For example, the EL-X1 10-track 1/2 inch tape uses
1/2 inch instrumentation type reels (same as professional audio reels) which have a bigger

I believe that this photo shows a Datamatic 1000

1/2" drive.

Hub size looks small on the 1/2" for later style tapes. 2" tape? I
wonder if that was linear? Had to have impressive motors.
