tomknight··on Operating the Lisp Machine (1981) [pdf]
Well, many of the concepts of the lisp machine are extremely relevant to the current design problems of today's CPUs, primarily around security and privacy. The continuing disaster promulgated on the world by languages such as C can only be solved by enforcing type safety and bounds checking in hardware. There continues to be progress in making these easier and more efficient to implement. I'd suggest looking at the SAFE architecture papers, especially the low-fat pointer paper: http://www.crash-safe.org/papers.html

Well, most of it was 74S series for the faster logic. 74F was not available at the time the machine was designed. The disk was a Fujitsu 80 Megabyte wonder. Who knew you could possibly make them that large in such a small rack sized unit. Here's one for you: Who made the CORE memory for that machine?

I've never seen a founder end up with preferred shares. Lots of shares, sure, but not preferred.

As one of the machine designers, it is gratifying to see continued interest. My favorite feature which I miss daily is the WHO line, with run bars and mouse documentation lines. And, of course, the correct placement of rubout along with the missing meta, hyper, super modifiers.
