CADR4 current status is we are optimizing the simulation runtime (it takes about 10 minutes to run through almost all the boot PROM to the point we are accessing memory -- which isn't fun when you want to work on accessing memory).

Someone should write some microcode and supporting code to make it possible to run / on the

CADR4 is now running almost through the whole boot PROM!

Now work to add disk, and memory .. and a bus.

@lfa I've been restoring / working on the for .. 20+ years now. I've never had the real thing, there are maybe four machines left in the world. N/A?

It's crazy how advanced the graphics software on Symbolics LISP machines were in the 1980's before SGI kind of took over that space.

Bootstrapping is slower than recompiling all of the system four times.

Anyone got any TTLDM-100 (by Electronic Component) in their stash? Other delays would work .. and wants to send me one or two.

@screwlisp Thought you would be interested in this.

On the ex-Symbolics employees mailing list somebody posted a link to a "history of the Lisp machine".

It's kind of long and so I didn't watch the whole thing, but just skipped around a little bit. Somebody else who did watch it said,

'Fascinating exposition. Given his mispronunciations of "CADR" and "Macsyma", it's clear that he wasn't in the room where it happened, nor spoke to anyone who was. But I can't quarrel with his research or cause-and-effect analysis of both the industry as a whole and Symbolics in particular.'

The document preparation system of Symbolics Lisp Machines consisted of two main hypertext tools, the Concordia authoring environment and the Document Examiner documentation browser and delivery interface. These papers describe the tools.

You know how and can do it with a chisel, but what you're presented with is a monster CNC machine to just make a simple square. (It is why I like "retro" computing, -- I can hack without having to spend several months on just using tools to do shit I know how to do).
