All, I picked up a big lot of stuff this past weekend.  Amongst the pile of quite desirable Apple items (Feb '84 Macintosh!!!) were versions of "Canvas" graphics software for Windows.  Boxed versions of Canvas 3, 5 and 6. Free if anyone wants it.  Comes with training material on VHS tapes!

It's always struck me how revolutionary (for IBM) the change in architecture from the 700x to the S/360 was. The 709x will probably strike the average reader of today as being arcane, what with sign-magnitude representation, subtractive index registers and so on. The 7080, probably even more so.
