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. -G On Sun, Mar 25, 2018 at 7:56 PM, emanuel stiebler wrote: > On 2018-03-20 11:56, George Michaelson wrote: >> I got given the last generation PDP-11 on a chip, in a 72pin DIP.
