from Linux Professional Institute - Board Chair

Jon "maddog" Hall currently is the Board Chair of the Linux Professional Institute.

Starting in 1969 (a half-century ago), Mr. Hall has been a programmer, systems designer, systems administrator, product manager, technical marketing manager, educator, author, CEO and consultant.

Mr Hall concentrated on Unix systems since 1980 and Linux systems since 1994 (a quarter century ago), when he first met Linus Torvalds and correctly recognized the commercial importance of Linux and Free and Open Source Software.

Mr. Hall is an author of numerous magazine and newspaper articles, many presentations and one book, "Linux for Dummies". He writes for Linux Pro Magazine and occasionally blogs for them.

Mr. Hall has traveled to over 100 countries, speaking on Free and Open Source Software. He received his BS in Commerce and Engineering from Drexel University (1973), and his MSCS from RPI in Troy, New York (1977).

Was GNU/Linux the first operating system? Was Unix? Did Unix and GNU/Linux spring from the minds of its developers fully formed? Of course not! They evolved over many years, developed on many computers that are now either non-existent or only existent in museums, turned off or out of reach for most of us.

Or maybe not.

Through the use of SIMH (http://simh.trailing-edge.com/), a hardware simulator built over many years by different people, you too can run early operating systems (http://simh.trailing-edge.com/software.html) in binary form and see how these operating systems worked and evolved. YOU can even write new programs for many of them, even in the assembly language of the old machines.

SIMH can run on on a variety of different systems, so you can run it on your favorite laptop or desktop including Raspberry Pi support.

Unfortunately there is no direct Android or iOS support, but you can access SIMH (and the old operating systems) from your phone running on a laptop or desktop through ssh and vnc.

Come to this talk for a walk through this amazing piece of work and a peek at some of the hardware architectures and operating systems that SIMH supports.
