- Desktop CYBER
Desktop CYBER (DtCYBER) accurately emulates a range of
Control Data Corporation (CDC) CYBER mainframes and peripherals in software.History
The CDC CYBER range of mainframe/super-
computer s were the primary products ofControl Data Corporation (CDC) during the 1970's and 1980's. CDC has ceased manufacture of CYBER mainframes in 1992.Once modern desktop systems became powerful enough, some former users of CDC CYBER mainframes tried to create software emulations of these computing dinosaurs.
The first commercial emulator was developed by Infoware (Cocoa Beach, Florida). In 1995 their product called AlphaCYBER ended up in the courts because CDC sued them for copyright infringement [ [http://www.highbeam.com/doc/1G1-17290895.html] Control Data obtains injunction against Infoware ] [ [http://www.fenwick.com/docstore/Publications/IP/Look_&_Feel.pdf] A Comprehensive Current Analysis of Software "Look and Feel" Protection ] . A settlement was reached before the case went to trial. The terms of the settlement were kept secret.
The court case frightened many would be emulation developers. A few years later in 2002 several former CDC CYBER users independently developed emulations of CDC CYBER mainframes. Only one emulator has been released. DtCYBER version 1.0 was [http://groups.google.com.au/group/comp.sys.cdc/browse_thread/thread/ae0091aef928bda9/a6000077d82a8cfd?hl=en#a6000077d82a8cfd released] by its author Tom Hunter from Perth, Australia as an open source product in December 2002. Initially it only worked under 32-bit versions of
Microsoft Windows , but later [http://groups.google.com.au/group/comp.sys.cdc/browse_thread/thread/94f53f4861fba804/cbf031fbcf7a3ff0?hl=en#cbf031fbcf7a3ff0 releases] added support for mostPOSIX compliant operating systems with X11 support.Although initially the software was distributed under an open source (BSD-like) license, in 2006 the author decided to turn the software into a commercial product.
