Remember those model 30 parts I was trying to give away/swap. Here is a picture of a model 30 installed in a system you have probably heard of: http://en.wikipedia.org/wiki/Xerox_Alto You could have knocked me over with a feather. Of course the article describes this as the system "hard disk", and I guess it was. When I was using them in the mid to late '70s we were using them like floppies and running the mini on a 40-80 MB removable drive. Gil
