PDP-10

inviting PDP 10 enthusiasts to use a new system that Paul Allen purchased called an XKL toad one, which is a PDP 10 clone I had it running tops 20 and which is a deck operating system, and invited people to recover software and get it reanimated on the system.

Paul's particular interest was getting his development tools that were used for the language packages at Microsoft and then the Altair Basic that he simulated on PDP-10 at Harvard.

So the Toad ran as a public access node rolled into PDP Planet from 97, 2005, and then it became the cornerstone of living computers in 2012, and it was on public display in XF.

That goes up to the opening of the public museum, but you can see that's a pretty long timeline to go from 1997 with an idea There was even a mini museum at the Natural History Museum in Albuquerque, New Mexico called Startup that went through the details of MITS and early Microsoft when they were in Albuquerque.

And he would probably laugh because he knows this.

So Cisco Systems, which Len Bosak founded, had this machine, this 2065, that served as their main deck system machine.

The story of Cisco, and I hope this is just the really quick story, is that Cisco was founded to make a faster 10, faster PDP-10 machine.

And they ended up getting into switching and then switching became the bread and butter.

In the first days of 1969, a group of student protesters occupied Ford Hall at Brandeis University.

That building housed the campus' telephone switchboard and their huge PDP-10 computer.

The protesters' demands were simple.

Brandeis had been recruiting minority students.

They didn't even hold a meeting or hearing for faculty to discuss the matter, so students held a peaceful protest.

On January 6th, they occupied Ford Hall, denying access to the computer room and the switchboard.

Meeting minutes show that at least one operator was turned away from the hall, physically prevented from accessing their beloved PDP-10.

And make no mistake, this was a proper machine.

Right.

So Paul Allen actually had to write an emulator program on a massive PDP-10 mainframe at Harvard just to simulate how the Altair's chip would behave.

That is insane.

It really is.

yes.

But never did I think I would have to compete with a PDP-10 computer.

And he says it was crushing, but I understood.

And then this composition, you know, his first composition to use FM and specialization was called Sabalite.
