If you mean the LMI Lisp machine: http://bitsavers.trailing-edge.com/pdf/lmi/

There's significantly more for the TI Explorer Lisp machine: http://bitsavers.trailing-edge.com/pdf/ti/explorer/

And even more for Symbolics: http://bitsavers.trailing-edge.com/pdf/symbolics/

Xerox did a Lisp machine line: http://bitsavers.trailing-edge.com/pdf/xerox/interlisp/

There's a working emulator for the MIT CADR: http://www.unlambda.com/cadr/index.html

And you can of course run Genera in an emulator: http://www.unlambda.com/download/genera/

There's a semi working TI explorer emu: http://www.unlambda.com/lispm/

There is an emulator for the Xerox machines.

There is a working TI explorer emulator: http://www.unlambda.com/index.php?n=Main.Meroko

An updated version of the MIT CADR emulator: http://trac.common-lisp.net/mit-cadr/browser/

Source trees for the LMI and TI machines are also on the web.

Without usable licenses.

I have been told that TI have given formal permission to redistribute their code, I will chase up the person who got hold of it to get it properly labelled.

The LMI stuff is more interesting to me as it is complete, I'm still a fair bit of work away from being able to build it though. I have spoken with RG about it but we didn't discuss the licence.

Texas Instruments sold their computer systems division at the start of the 1990s. I've read that that sale did not include the Explorer copyrights.

At the start of 2011 I got in touch with Robby Holland, then the head of TI's patent licensing division. Holland could not find anything about the computer systems division, or anything about the sale, or whether they owned the rights anymore. They did not have any of the project materials on hand. Holland said he would have someone look into the archives. When I tried to get in touch with him a few months later Holland was no longer with Texas Instruments.

Texas Instruments closed their Lisp Machine activities in 1990. Nobody picked that up.

There is an extremely large amount of TI Explorer code with lots of later stuff written by TI:


No usable license so far.

Yes, that is the stuff that I have been told has been released by TI. I will try to get a proper licence added to it.

The microcode sources are missing and one of the files for NFS is truncated.

Yes that was it.
