Remembering RAMAC

[Dave Brown]

Still have a partial copy of the handbook here for a GI (general 
instruments) 500FR 14 inch single platter HDD- 16 megaBITS capacity, 
platter spun up to 3600 rpm by a 'small' 1/2 HP motor. Dates on the 
drawings range from early 1971 to 1974. The platter is still 
here-makes a nice gong. The box this was in was std rack width and 
about 8-10 inches high-and nearly three feet front to rear!
