The Web Site to Remember National Semiconductor's Series 32000 Family


Oberon is the operating system of the Ceres family of computers. Oberon and Ceres were developed at the ETH Zürich by Professor N. Wirth in the 1980's. He wrote a book about Oberon which contained the source code of it! Unfortunately I still don't have the book.

The concept behind Obereon is very interesting. Oberon was from the beginning based on a graphical user interface (GUI) with a high-resolution black-and-white screen and a mouse interface. Don't forget that most computer interfaces of that time were text based, e.g. DOS or Terminal. Despite its capabilities Oberon was very compact and fits in 128 kbytes memory.

What I have is the EPROM content of two Ceres-3 machines. Surprisingly they are different. Together with the description of the Ceres-3 it should be possible to rebuild such a system based on the M32632 CPU. This will be a nice project to do.
