SPITFIRE was written in Turbo Pascal with Assembly Language routines. It was released in 1987 under the Shareware concept and had a moderate sized fanbase, only outnumbered by products such as RemoteAccess, TriBBS, PCBoard, Major BBS, and Wildcat! BBS. It was possible to run multiple "nodes" of SPITFIRE under Microsoft Windows and OS/2; although, most SysOps preferred to use Quarterdeck's DESQview for this purpose. SPITFIRE interfaced with message relaying systems such as FidoNet through 3rd party utilities such as SHILOH, a QWK networking interfacing program, and BCSUTI, a Postlink-style networking interface.
SPITFIRE's most successful release (Version 3.2) came in 1992, just before the World Wide Web exploded on the scene. By 1994, many SysOps began converting from running BBSes to becoming Internet Service Providers. Mr. Woltz was greatly admired by loyal SysOps, but was known for being somewhat stubborn. Due to his unwillingness to add Internet connectivity to the software, SPITFIRE's usage dwindled significantly throughout the United States. It was and is still used throughout the world, particularly in countries where high-speed Internet access is unavailable or banned.
SPITFIRE (version 3.6) was updated in 1999 for Y2K compliance. Current release is SPITFIRE 3.7 (as of 1 January 2010) which is still supported by Buffalo Creek Software today.
