I never ran it. It was a huge, ceramic enclosed DIP.
Ginormous.
BIggest chip I'd ever seen. I think it required dual voltages.
I can see specsheets for what is called a J11. I don't think I
remember it looking like that, but it was a long time ago.
That's why I was asking. I know the J11 pretty well, with it's 60 pins,
it is big. Was curious about a bigger one ;-)
Cheers & thanks!

I got given the last generation PDP-11 on a chip,

gave it to somebody else who could use it. At the time, I thought it
was Teh Awesome l33t to have an entire pdp11 on one chip. imagine! my
god, the power, the power. I think the day is coming when a CPU has
gold pins top and bottom. they have a very large number of pins.
Somebody smart will have to invent code to work out how to wire the
pins. Oh, hang on, thats why Djikstra's algorrithm which lies at the
heart of routing protocols was written back in the day. oh dear.. its
turtles all the way down isn't it?
Could you tell us more about this 72-pin version of a pdp11?
