This first place to look for information about old computers is

Now that there is (or seems to be - I was unable to test) a reasonable
emulator for the Alto, it would be nice if some disk images for it were
publicly available. Specially any Smalltalk related ones.
Since Sketchpad only ran on a single computer in the whole world, even
in its day most people exposed to it experienced it as movies instead of
a live demo. These movies are available today. Certainly an emulator
would be nice, but the i/o devices on PCs are different enough from the
TX-2 that I don't know how realistic the experience would be. Even a
Vectrex (an interesting videogame from 1982) emulator is rather
different from the real thing (which I had the pleasure of seeing in
action live about four years ago)..
