Schoonschip is an algebraic manipulation program which was designed for large problems, originally in particle physics, and which pioneered a number of the concepts now generally used in algebraic computation. Its interface is not as slick as some of the "modern" symbolic manipulation programs, and it does not have as many built-in procedures as some of them do, requiring the user to construct more of his own. But it is written in machine language and is fast, capable, and efficient in its use of machine resources. The program runs in approximately 650 kilobytes of memory.
The distribution for each machine consists of 2 compressed archive files, one of which contains the binary executable and is machine specific, and the other of which contains text files with examples and a manual, the same for all machines. These are available for the Atari, Amiga, Sun 3/60, and NeXT computers, with 680x0 cpu's, via anonymous ftp under the directory "physics/schip" at archive.umich.edu Although freely available, the executable code is copyrighted by its author, M. Veltman. Schoonschip running under a beta version of a CLI shell (not in the public domain) is available for the Macintosh (and for the PowerMac, M68000 emulation mode only) by special request for scientific purposes from Prof. M. Veltman Physics Department University of Michigan Ann Arbor, MI 48109 or Prof. David N. Williams Physics Department University of Michigan Ann Arbor, MI 48109 David.N.Williams@umich.edu An indexed, hard-copy manual is also available at reasonable cost.
