The "EA IFF-85" Repository

• IFF docs

  The original Electronic Arts IFF docs with some revisions from Commodore Business Machines.

  Thankfully, Commodore converted the docs from MacWrite to Word format -- the *.doc files in this repository. I converted those to .docx (MS Word format), .pdf, and .rtf files.

  • EA IFF 85.pdf: "EA IFF 85" Standard for Interchange Format Files defines the IFF standard and explains the strategy of saving data in an extensible interchange format rather than dumping a program's internal state in a fixed format.
  • IFF Quick Intro.pdf: A Quick Introduction to IFF is a quick introduction for programmers in the 1980's.
  • ILBM.pdf: "ILBM" IFF Interleaved Bitmap defines the raster image format (interleaved bitplanes) that's used heavily on the Commodore Amiga.
  • 8SVX.pdf: "8SVX" IFF 8-Bit Sampled Voice defines an 8-bit sampled sound format.
  • SMUS.pdf: "SMUS" IFF Simple Musical Score defines a simple musical score format.
