The complete history of the driver is rather cloudy. The following is probably incomplete and inaccurate.
Apparently, Per Lindqvist (pgd@compuram.bbt.se) first got an ATI driver working with an early ATI card under X386 1.1a. This original driver may have actually been based on an non-functional ATI driver written by Roell. Then Doug Evans (dje@cygnus.com) ported the driver to the ATI XL, trying in the process to make the driver work with all other ATI cards.
Rik Faith (faith@cs.unc.edu) obtained the X11R4 driver from Doug Evans in the summer of 1992, and ported the code to the X386 part of X11R5. This subsequently became part of XFree86.
I (Marc La France) have since taken the driver over after Rik got rid of his VGA Wonder card.
The major reference that was used was a manual from ATI:
"VGA WONDER Programmer's Reference" ATI Technologies, 1991. Release 1.3 -- Reference # PRG28800-13
However, Chapter 11 (ATI 18800 ATI VGAWONDER) of George Sutty and Steve Blair's "Advanced Programmer's Guide to SuperVGAs" (Brady/Simon & Schuster, 1990) was also useful. Further, someone e-mailed Rik a random document from the ATI BBS which was dated 3Jul91 and which may have been named PROGINFO.DOC.
