    TCS Legends | Mark Todes: technologist and monopoly slayer

    Mark Todes has a fascinating story to tell. The South African technologist and entrepreneur is TechCentral’s guest in the final episode of season 1 of the popular TCS Legends podcast.

    Todes, who is perhaps best known for helping fight Telkom’s attempts in the 1990s to extend its telecommunications monopoly to the internet, has a storied career that began in the mid-1970s in the pre-PC era of mainframes and minicomputers.

    In this episode of TCS Legends, Todes tells TechCentral editor Duncan McLeod about the founding of Compustat with his long-time business partner Mendel Karpul and how they went on to develop a word processor called GhostWriter (the name of which Microsoft later tried to wrestle away from them).


    TCS Legends is powered by Mitel. For all your Unified Communications and Customer Experience needs, visit Mitel.com.


    In the show, Todes chats about:

    • How he and Karpul got their start selling a bureau-based accounting solution for pharmacies – and how they got their first big break. The solution was developed in Fortran using punch cards and ran on a minicomputer from Digital Equipment Corporation;
    • Their development of Survey 2000, a cadastral land surveying system – their first product for personal computers (developed by Hewlett-Packard, prior to the launch of the original IBM PC);
    • The development of GhostWriter, which became an early DOS-based competitor to the likes of MultiMate, WordStar and WordPerfect.
    • The launch of Internet Africa, a pioneering South African internet service provider that was later sold to Datatec (and later to Naspers);
    • The early days of the internet industry in South Africa, the formation of the Internet Service Providers’ Association and the existential fight with Telkom over whether the telecoms operator’s government-sanctioned monopoly included the provision of internet services;
    • Working with Naspers, Mweb and the late Antonie Roux;
    • The launch of Korbitec (and its later sale to Naspers); and
    • How he and Karpul became early pioneers in the CD-ROM business.

    There’s much more than this to Todes’s story, making him one of the true legends of South Africa’s technology industry. Don’t miss this concluding episode of season 1 of TCS Legends. The series will return for season 2 in 2025.
