ALGO for Bendix G15

  • Anonymous. ALGO : Algebraic Compiler for the BENDIX G-15 General Purpose Digital Computer.Bendix Computer Division of The Bendix Corporation, Manual T21, August 1960, 28 pages. PDF at

    "Algo follows the principles laid down for the universal algebraic computer language, Algol, proposed for international use by computer organizations in America and abroad.

    The Bendix Corporation is happy to cooperate with the Assocation for Computing Machinery and with the other members of the Algol committee in being the first manufacturer to introduce a programming system patterned on their proposal."

ALGOL 30 for LGP-30 (Dartmouth College)

  • T. E. Kurtz. BASIC. In History of Programming Languages I, R. L. Wexelblat, Ed., pages 515-537, 1981. ACM Digital Library

    "At the same time E. T. Irons, then a graduate student at Princeton, spent the summer in Hanover while working on a syntax-directed compiler (Irons, 1961). Our attention was thus drawn to the International Algebraic Language known also as ALGOL 58. A group of four students (Stephen Garland, Robert Hargraves, Anthony Knapp, and Jorge Llacer) and I began to design and construct an ALGOL 58 compiler for the LGP-30. A paper (Samelson and Bauer, 1960) discussing what is now known as bottom-up parsing, provided the efficient scanning algorithm needed for a slow and small computer. Shortly, ALGOL 60 appeared (Naur, 1960), and our effort shifted to it.

    Since the limited size of the LGP-30 precluded a full implementation of ALGOL 60, certain of its features (arrays called by value, own arrays, strings, variable array bounds, and recursion) were omitted; but we did include parameters called by name, using "thunks" (Ingerman, 1961; Irons and Feurzeig, 1961), and integer labels. We dubbed our work ALGOL 30, since it was for the LGP-30 (Kurtz, 1962a, Feb., 1962b, Mar.)."

Burroughs 205

"Burroughs had this computer called the 205, which was a drum machine that had 4000 words of memory instead of 2000, and they needed a compiler for it. ... I said I’ll write you an ALGOL compiler for $5,000, but I can’t implement all of ALGOL. I think I told them I can’t implement all of ALGOL for this; I am just one guy. Let’s leave out procedures -- subroutines. Well, this is a big hole in the language! Burroughs said, “No, no -- you got to put in procedures.” I said, “Okay, I will put in procedures, but you got to pay me $5,500.” That’s what happened." [Don Knuth, CHM Oral History, 2007, page 9]

  • Paul Kimpel. retro-205 Emulator project.
    Kimpel has written an emulator for the Burroughs 205, and has been able to execute two versions of Knuth's Algol 58 compiler on the emulator. Kimpel reconstructed one version from the late-stage development listing Knuth donated to the Computer History Museum; the other version was from a listing belonging to Tom Sawyer of a numeric dump of a production binary tape. Unfortunately the first version lacks the entire library, and the second version contains only the first overlay of the library.


Burroughs 220 (BALGOL)

"I’m in my second year at Cal Tech, and I was a consultant to Burroughs. After finishing my compiler for Burroughs, I joined the Product Planning Department. The Product Planning Department was largely composed of people who had written the best software ever done in the world up to that time, which was a Burroughs ALGOL compiler for the 220 computer. That was a great leap forward for software. It was the first software that used list processing and high level data structures in an intelligent way. They took the ideas of Newell and Simon and applied them to compilers. It ran circles around all the other things that we were doing." [Don Knuth, CHM Oral History, 2007, page 9]

    "By now, I concluded that I would have to learn much more about computers, at a hands-on level. The opportunity was engendered by the evangelistic efforts of Al Bowker and George Forsythe to establish an intellectual and technical base for, and broaden interest in, computers throughout the Stanford campus. In company with the development of a new division, then department, of Computer Science, and of a campus-wide computer center, elementary programming courses were organized. I enrolled in the BALGOL (Burroughs Algol) course given by Bob Oakford, over the summer of 1962. This had much of the flavor of a course in English for fresh immigrants, the class having a very broad distribution of age and of academic status, specialty and sophistication." [Joshua Lederberg.

JOVIAL (Systems Development Corporation)

"At Systems Development Corporation, programming systems had to be developed for a large command and control system based on the IBM military computer (ANFSQ32). The resulting Algebraic language with fairly elaborate data description facilities was JOVIAL (Jules Schwartz' own Version of the International Algebraic Language). By now compilers for JOVIAL have been written for the IBM 7090, the Control Data 1604, the Philco 2000, the Burroughs D825, and for several versions of IBM military computers." [Rosen 1964, page 7]

MAD (University of Michigan)

"The University of Michigan developed a compiler for a language called Mad, the Michigan Algorithmic Decoder.26-27 They were quite unhappy at the slow compiling times of Fortran, especially in connection with short problems typical of student use of a computer at a University. Mad was originally programmed for the 704 and has been adapted for the 7090. It too was based on the 1958 version of Algol." [Rosen 1964, page 7]

NELIAC (Naval Electronics Laboratory)

"The Naval Electronics Laboratory at San Diego was getting a new Sperry Rand Computer, the Countess. With a variety of other computers installed and expected they stressed the description of a compiler in its own language to make it easy, among other things, to produce a compiler on one computer using a compiler on another. They also stressed very fast compiling times, at the expense of object code running times, if necessary. The language was called Neliac, a dialect of Algol. Compilers for Neliac are available on at least as great a variety of computers as for JOVIAL." [Rosen 1964, page 7]

ZMMD (Zurich, Munich, Mainz, Darmstadt)

"In the fall of 1955, we [Bauer and Samelson, at Munich University] had already started a joint project on designing a universal language for program exchange; this was stimulated somewhat later by plans that Springer-Verlag, Heidelberg, had about publishing a handbook of algorithms. From the beginning, we intended to build appropriate compilers; this became inevitable when we heard rumors that Piloty’s plans for PERM II had been dropped. Our compiler design was based on our stack principle and on Rutishauser’s experience [at ETH in Zürich] with run time organization. We were soon joined by Hermann Bottenbruch from Alwin Walther’s institute in Darmstadt.

As mentioned above, in 1956 Rutishauser, Samelson, and myself started the design of a compiler with a single language for machines as different as the Munich PERM, Zurich ERMETH, and (later) the Mainz Z 22 ('ZMMD-Project'). Compiler design and programming language design went hand in hand. In the fall of 1957, we had the plans ready which allowed us to approach the ACM. This led to the Zurich Conference in May 1958. Our input (Bauer and others 1958) to this international joint effort was a direct consequence of the cellar principle of state transition, which, originally meant for (arithmetic) formulas, was extended to the whole language and was expressed in the form 'postpone as long as necessary, reduce as soon as possible.' But we aimed not only at having the language restricted so that it could be parsed 'sequentially' by a pushdown technique, which turned out equivalent to requiring a context-free grammar, but also postulated to attach the semantics to the syntax. ...

For ALGOL 58, the ZMMD compilers worked by the end of 1958. Following the ALGOL Conference in Paris in January 1960 that produced ALGOL 60, we had adapted our compilers in Mainz, Zurich, and Munich within a few months. The ALCOR group (Samelson and Bauer 1962), formed after the 1959 Paris Congress, expanded rapidly. The members were given the available ZMMD material on translation methods, and they began their own work on compilers. The undertaking had considerable commercial and educational effect."

  • "Rutishauser [4] was first in recognizing that an effective solution of the programming problem requires introducing conventional notation (commonly called "problem oriented language" today) into programming and having the computer do all subsequent phases of translation work. His proposal published in 1952 [5] and the subsequent work of Böhm [14] found no immediate response. The first large scale programming systems with formula translating features, PACT [3] and FORTRAN [2], were developed as late as 1955. Methods used, however, were not published at that time. At about the same time the computer group at the Technische Hochschule in Munich, fully acquainted with Rutishauser's ideas, started discussions of the subject of formula translation. However, interest was centered on methods feasible for computers far inferior in capacity and speed to, say, the IBM 704. For this purpose a sequential translating technique based on independent previous investigation [6, 13] was developed. Since 1957 work was continued within the framework of today's ZMMD (Zűrich-Munich-Mainz-Darmstadt) group. The basic aim was development of a common language (and translator system) for different computers. This finally led to the creation of a joint committee of the ACM and the GAMM, which in 1958 proposed a common algorithmic language--ALGOL [11, 12]. In the meantime the structure of the translator of the ZMMD group was frozen, and coding of the system (called ALCOR = ALGOL COnverteR) for the computers involved (ERMETH Zűrich, PERM Munich, Z 22/2002 Mainz, 650/DERA Darmstadt) and for a number of computers in cooperating scientific institutions in Austria, Germany, and Denmark was begun. Pilot models of the translator have been working satisfactorily in Mainz, Munich, and Zűrich since the fall of 1958."
