Software Preservation Group (SPG)

"I want a community of indiana jones types who are out
there fiercely collecting artifacts before they turn into dust." 


The Software Preservation Group (part of the Californian Computer History Museum, CHM) is an informal global association of people interested in the digital curation of computer software artefacts.

This page captures retroComputingTasmania's efforts to contribute to activities like the SPG, targeting artefacts that we would like to see preserved. 

One of our interests is recovering the execution environment of a digital artefact so that it can be experienced using emulators. The execution environment typically includes the host operating system, the compilation or software development support, and the associated toolchain or libraries needed for the artefact to function. 

The table below shows the software preservation projects currently underway or completed.

The columns are defined as:

  • Digital artifact - the title of the software item, this column (mostly) links to a project specific webpage with more detail.
  • Found? - whether the item has been located and in a format that has some prospect of recovery
  • Recovered? - has the item been recovered into a modern digital format (PDF, text-files).

Our preference is to process copies of originals (either digital scans or photocopies), and that the originals be sent to well known repositories, such computer history museums or national archives.
