Class of 78 is exactly right.

The Edusystem was gone by the time I got there. I worked on the PDP/8e and 
later the VAX.

I did something similar, but I heisted a hazeltine terminal from the lab 
(Dr. Levine said I could.)

Don't let the smoke out!

I have my DECTape from the PDP/8e at UWM. I have no idea if it's still 
readable. All I had on it were BASIC programs and one or two assembler 
programs I cobbled up.  I may have a photo from NHS somewhere.

I can't remember how the racks were arranged. That was a LONG time ago.

I must have some of that stuff in my storage locker. I'll have to check.

Any relation to Mary Miles, and her younger (?) sister?
