There has been some discussion on comp.os.cpm regarding the replacement of 8"
drives with 3.5" drives because they apparrently have the same pin-outs and
can be used as transparent replacements.  (Note that I have not followed the
discussion in all detail, so I may be mistaken.) I have now discovered, after
being very bored one night, that the PDT-11/150 which has been sitting in our
storage closet works.  However, the 8 inch drives in it are very noisy and
slow.  What I was wondering was if anyone knew whether or not it is possible
to replace the old 8 inch drives in this beast with modern 3.5 inch drives. 
Of course, I realize that I would have to transfer all the software from one
format to the other.
