Hello Keith:

   I recall that 8" units were around 300kb. I remember a unit at one place
I worked that was the ne-plus-ultra for the day, as it had dual 8" drives.
Of course it was off in it's own box (nearly the size of a CPU) next to the
cpu. Closing both drive doors had to be done standing up as you had to
really put your back into it and made a very impressive klunk..

Thanks, Ed Kennedy
