Which 680x0.library is recommended?

  1. For GVP-m TekMagic/QuikPak products: Ralph Babel's v2.3 library (below) is the one to use, with Thomas Richter's Mu680x0Libs.lha a suitable second. Both work with the MuLibs development tools.
  2. For most non-GVP-m 040/060 boards: Providing that they don't have a recently updated set of libraries, or 68040 boards that have been updated to a 68060 with an adapter, again, Thomas Richter's Mu680x0Libs.lha is a relatively good option.
  3. For application/OS development: The MuLibs CPU libraries integrate well with the dev tools Thomas Richter has updated and ported. For PPC-based products, Phase5's libraries are recommended due to their handling of both the PPC and the 68060—something that is not publicly documented.
  4. For historical reference and source code: A plus for anyone that wants to develop going forward, Carsten Schlote's sources for the mc68060.library are available, which are reportedly usable with all MC68060 CPU cards on the Amiga. Warning: Please note that Carsten's code hasn't been updated since its creation in the late 1990s, despite being posted in 2016 on Github. Both CPU bugs and AmigaOS compatibility/changes have been encountered since its last compile, so it may not be suitable without updates.
