TENEX Interlisp

Tom Rindfleisch kindly supplied a set of TENEX Interlisp files from a system dump of the SUMEX-AIM <lisp> directory as of January 31, 1982. Tom notes:

This version of Interlisp should be both TENEX and TOPS20 compatible. It came at a time when lots of work was going on to port Interlisp to other environments, including the VAX and the new personal Lisp machines (Dolphins, etc.). This means little was changing in the TENEX/TOPS20 version.

There are links to these files here.

Speaking of TENEX Interlisp, TWENEX.ORG is offering free TENEX accounts on a simulated KL10B and they seem to have a version of Interlisp installed. I plan to investigate.

Progress with Lisp 1.5 source

Rich Cornwell (some of whose work I reported on earlier) and Bob Abeles (who was the first to point out to me the existence of the Fortran II sources) have recently completed a reconstruction of the card deck for the “Bonnie’s Birthday Assembly” of Lisp 1.5 (see Pascal Bourguignon recreates machine-readable source for LISP 1.5). Rich notes:

Bob Abeles has finished proof reading Lisp-1.5 and is pretty confident that the binary matches the listing. Unfortunately it still does not run. So we need someone with more lisp experience or possible compare it to some of other versions you have listed on your Lisp site. It currently does not work correctly under sim3.6 due to card reader bug. I will get this fixed in next couple of weeks. … But after two people proofing it (Bob & me) I am pretty sure that it matches now.

It is also possible that the lisp interpreter works correctly, but my test jobs is wrong.

Rich’s files are here if you’d like to take a look.

My name is Paul McJones. I am using this weblog to discuss historic computer software and hardware among other topics. For several months I’ve been studying the early history of Fortran, and trying to track down the source code for the original Fortran compiler. Although I just set up this weblog recently (June-July 2004), I’ve created back-dated entries to document my quest in chronological order, starting here.

I welcome suggestions for additional topics, and also would like to invite others to contribute articles on the history of early programming languages, operating systems, database management systems, and applications.

If you like this web log, you might be interested in the System R website documenting the history of the System R relational database research project, which gave birth to the SQL query language.
