Bitstream Speedo, or Speedo, are an obsolete scalable font format created by Bitstream Inc. Speedo was used on Atari ST, Falcon, in the XyWrite word processor, and in very early versions of WordPerfect and Microsoft Windows. Speedo was replaced by more popular font types like Type 1 fonts. Although Speedo is obsolete it is still supported by the X Window System through the speedo module, and most Linux distributions have a Speedo font package. Speedo fonts have the file extension .spd.
