  van der Poel was the designer of the early Stantec ZEBRA computer, and van der Mey implemented ALGOL and LISP for the ZEBRA.

  "The operating system is relatively small, and programs require less space [than with DECUS 8-102a] since a distinction is made between program and data. This is less flexible and leads to irreconciliable differences between LISP 1.5 and LISP-8, but it is more efficient for a small computer such as a PDP-8."

• Larry Davis. LISP 1.5 Interpreter for PDP-8 with OS/8. Washington University. DECUS Number 8-628. Source and executable versions. Online at dbits.com Online at bitsavers.org

  "Modified version of DECUS NO. 8-102A for use under OS/8 (PS/8). OS/8 file input and output is allowed, which enables the user to prepare LISP programs using OS/8 EDIT. Input and output in ASCII. Facilities for writing own code in assembler to be added to the interpreter for evaluation of special functions are provided for."

  Modified by Davis on January 28, 1972 and March 9, 1972; modified by Torbjorn Alm, Autocode AB, on May 15, 1973; submitted to DECUS by Robert Hassinger, Liberty Mutual Research Center, Hopkinton, MA.

  "This is an 8K version of the LISP Interpreter (see DECUS No. 8-102). Only the differences are given in the documentation so it would be well to request the 8-102 write-up as well."

Uppsala Lisp: F1, F3 and F4

Mats Nordström and his colleagues at the University of Uppsala in Sweden developed a series of Lisp implementations written in Fortran.

"LISP 1.5 INTERPRETER WRITTEN IN FORTRAN
    A simple Lisp 1.5 interpreter has been written in Fortran by Mats Nordstrom at Uppsala University. The system follows closely the definition of eval given in the Lisp 1.5 User' Manual; in particular, it uses an A-list (rather than a linear stack for variable bindings). Some 'modern' features have been included, such as nospread lambdas and implicit progns.
    The interpreter is oriented toward interactive use, but with minor modifications it can be used in batch mode. It is intended for those who want to implement Lisp quickly and provisionally for a new computer, and for tutorial purposes in teaching interpreters and Lisp implementation. The program is carefully commented and documented. Educational and research institutions can obtain a copy free of charge by writing to the following address: Mats Nordstrom, Datalogilaboratoriet, Sysslomansgaten 25, S-752 23, Uppsala, Sweden." [SIGPLAN Notices, Volume 6, Number 5, July 4, 1971, page 6 (News section) ACM DL]

The original motivation was to be able to run Lisp programs on computers elsewhere in Sweden via a remote processing capability; the portability allowed these systems to be ported to various computers at Uppsala and elsewhere. Lisp F1 was compatible with Lisp 1.5 with extensions from BBN Lisp; it was written in Fortran IV and ran on IBM computers. Its development began in January 1970, and it was usable by September 1970; subsequent work increased its performance. Lisp F3 was compatible with INTERLISP, and thus could run many INTERLISP packages such as EDIT, MAKEFILE, BREAK, ADVISE and TRACE. Its development began in 1976. For more detail, see chapter 4 of Herbert Stoyan's book [Online at informatik.uni-erlangen.de].

Nordström produced a final version, Lisp F4, in the early 1980s; see below.

  Nordström supplied to McBride what is believed to be the final snapshot of Lisp F4, from August 22, 1983, with permission to distribute it. McBride includes Nordström's original code absolutely complete and untouched including documentation, Fortran source code, lisp code, etc. -- see the file lispf4.orig in the archive.
