Duluth News Tribune video from today

[Peter Peterson]

Hi all,

Here's the video from the dnt of today's demo:

Of course, they leave out our discussion of everyone who helped us along the way, but that's editing.

Anyway, a really nice feature on Dawson and the project.

Thanks to all for their support! The demo went very well -- standing room only on a Friday morning in summer!

That looks great!

Which "spacewar" is the one in the article.  I ask because it is clearly not POLY SPACEWAR [but few things are] yet this is to my reckoning NOT the silly little SPACEWAR that is part of the DEMO-12 programs that seem to be a topic of conversation.]

Eventually, I will get POLY SPACEWAR fully recovered and all can judge for themselves.

Also, I think the toy SPACEWAR doesn't even require EAE.

Since you people have an academic interest in the PDP-12 and thus the LINC instruction set, can someone explain to me EXACTLY what the LINC instruction MUL does when the I bit is set. [A knee-jerk response of "inverse multiply" is not what I want to hear.  I want a mathematically expanded explanation of what that does.  I don't know of any program that ever used it [perhaps because no one else knows what it does either!].

PDP-8 EAE has divide as well as multiply, but the LINC instruction set has MUL and MUL I.  Can someone explain this to me?  [It's an old bugaboo that has plagued me since 1970.
