Oral History Interview with John Brackett and Doug Ross
An Interview with JOHN BRACKETT AND DOUG ROSS OH 392 Conducted by Mike Mahoney on 7 May 2004 Needham, Massachusetts Charles Babbage Institute Center for the History of Information Processing University of Minnesota, Minneapolis Copyright, Charles Babbage Institute John Brackett and Doug Ross Interview 7 May 2004 Oral History 392 Abstract Doug Ross and John Brackett focus on the background of SofTech and then its entry into the microcomputer software marketplace. They describe their original contact with the University of California at San Diego (UCSD) and licensing the p-System which had been developed there. They discuss the effort required to bring the program to production status and the difficulties in marketing it to the sets of customers. They talk about the transition from 8 bit to 16 bit machines and how that affected their market opportunities. They conclude with a review of the negotiations with IBM and their failure to get p-System to become a primary operating environment. That, and the high performance of Lotus 1-2-3, brought about the demise of the p- System. [John Brackett requested that the following information from Wikipedia, the free encyclopedia, be provided as an introduction to this oral history interview: “UCSD p-System or UCSD Pascal System was a portable, highly machine independent operating system based upon UCSD Pascal.

The UCSD P-System STATUT ORIL Y EX E:M PT
DOCfi!D(ov~ by NSA on 12-01-2011, Transparency Case# 5335]UNCLASSIFIED The UCSD p-System STATUT ORIL Y EX E:M PT This paper discusses the UCSD p-System, an operating system for small computers developed at the University of California at San Diego. The discussion includes the overall system, file managing, editing, and programming in Pascal on the system. INTRODUCTION The UCSD p-System was developed at the University of California at San Diego to support Pascal programming on microcomputers. Similar to MS-DOS, the p-System is an operating system for small computers but is, in many ways, very different. The p-System is written in Pascal and now supports not only Pascal, but also FORTRAN, COBOL, BASIC, and Modula-2. The concept was to have an operating system that, once it was implemented on a machine, allowed any program written under that operating system to be truly transportable from computer to computer. That is to say, the p-System compiler would not actually translate the program into a language that was specific for, say, an 8088 chip on the IBM-PC, but rather would translate it into a "pseudo" language that, when used with an operating system designed for the PC, would run correctly. Similarly, if the operating system were implemented on a Digital Equipment Corporation (DEC) computer, this same pseudo code would still work properly with no modifications. The particular version of UCSD p-System tested was written for the IBM-PC and requires two single-sided double-density disk drives and at least 128K of memory. -

I will address the origin of the language, discuss the architecture, and talk about the language standards for unextended Pascal and Extended Pascal. I will confront the major criticisms of the language, explaining the origin and inaccuracy of the many myths about Pascal. Finally, I will address the Pascal implementations available today, comparing the 1 of 5 11/9/07 11:42 AM The Pascal Programming Language http://pascal-central.com/ppl/index.html different compilers and the different platforms on which Pascal is currently available. My experience with Pascal dates back to the PDP-11, the system used at Santa Clara University where I received my Bachelor of Science in Computer Science in 1984. During my college years, I learned and worked with several languages on campus, ranging from FORTRAN to Pascal, COBOL to Assembly. -

The Kerntest Package
The kerntest package Harald Harders [email protected] Version v1.32 (2004/04/14), printed 14th April 2004 Abstract This class makes it easy to generate tables that show many different kerning pairs of an arbitrary font, usable by LATEX. It shows the kerning values that are used by the the font by default. In addition, this class enables the user to alternate the kernings and to observe the results. Kerning pairs can be defined for groups of similar glyphs at once. Automatically, an mtx file is generated that can be loaded by fontinst to introduce the user-made kernings into the virtual font for LATEX.
