[Simh] Which PDP-11 to choose

[Clem cole]

19” form factor for the disks drive fir the space in the 19” relay rack.  You’re right the platters themselves were smaller.  The disks were referred too by the mechanical FF.  19, 8, 5.25 etc.   

Sent from my PDP-7 Running UNIX V0 expect things to be almost but not quite.
