Diagnostics were supplied on cassette tape.

I don't think that portrayal of Xerox's view on the mouse is correct. Much of
Interlisp and all of Smalltalk was mouse-based and Interlisp was never designed
for (only) use by youth.
Trackpads are fine except for detail work. Touchscreens are bound by touch
targets needing to be finger-sized. T

Pkunzip would automatically prompt you to insert disk 2, etc for spanned
