    Late 1960s to early 1970s
    Starting with a crystal set given to me as a Christmas present, I built several electronics projects, including the design and partial contruction of a serial microcomputer in Transistor Transistor Logic (TTL). See my Electronics Nostalgia page for details.

    1976-1989
    I am a nuts and bolts programmer. During the good old days of 8 bit microcomputers (SC/MP, 2650, Z80) and beyond, my favourite language was assembler. I spent my first decade in the workforce at Telecom Australia (now Telstra) as an electrical engineer. One of my earliest notable achievments was The Great Flight Simulator Hack of 1982. The 2650 was one of my favourite processors; I co-authored 2650 DOS with my friend Ron Harris.

    My interest in disassemblers started in the 8 bit microcomputer days. Inspired by Resource for CP/M (by Ward Christensen), a friend (Ron Harris) and I produced a highly modified and refined version for the Z80. [This program in turn inspired another program, much enhanced again, with the same catchy name, for the Amiga computer. It is written by Glen McDiarmid, and until recently was still commercially available]. I owned an Amiga computer (model 1000, later model 2000) from about its second year of availability (1988?).

    1990-1992
    I worked at Telecom Australia on a project called Drift. Drift is basically a multisession communications program with a scripting language, which was able to perform miracles with old mainframe software (legacyware) in Telecom. I found myself working on the low level aspects of Drift, such as writing a VxD (virtual device driver). I also took it upon myself to become the local expert on the Periscope (In Circuit Emulator) hardware that the section owned. You don't get much lower level than that, apart from microcode!

    1993
    My interest in disassemblers led me to work for a year at the Queensland University of Technology (QUT) on disassembly tools. Part of the work there was to support Cristina Cifuentes with her thesis project, a decompiler (reverse compiler) called dcc. During that year, I developed a method of identifying library code in executable files using signatures , and wrote a paper on the subject. This paper is published as "Identifying Library Functions in Executable Files Using Patterns", Proceedings of the 1998 Australian Software Engineering Conference, Adelaide, 1998. After the project, Cristina and I occasionally tinker with dcc in our spare time. This project has led us to an interest in binary translation of executables.

    1995-1999
    I wrote Windows Field Terminal (WFT) for Telstra as a contractor, with a lot of help from Andrew Sheppard of Telstra. The program does most of the features of the Dos Field Terminal (DFT), but with a more GUI feel, and is able to run multiple sessions on a single computer. I believe that WFT (and DFT) are still used by Telstra for managing some fault reports.

    1997-2001
    In 1997, Cristina Cifuentes received Australian Research Council (ARC) large grant A49702762 ("Migration of Legacy Software by Binary Translation"). I worked as a Senior Research Assistant to Cristina for the three years of the grant, and continued on with other research funds, notably from Sun Microsystems. The main output from this research is the University of Queensland Binary Translator (UQBT), released in 2002 under a BSD license, and research papers.

    2001-2007
    Following the tech crash, I started my PhD on decompilation.
