The project was also expanded to include other PC development-related information and therefore absorbed a number of independently maintained lists on PC I/O ports (by Wim Osterholt and Matthias R.

The project is the result of the research and collaborative effort of more than 650 listed contributors worldwide over a period of 15 years, of which about 290 provided significant information (and some 55 of them even more than once). The original list was created in
January 1985 by Janet Jack and

Ralf Brown maintains an astounding file which is chock-full of detailed, absolutely-indispensable information for DOS programmers on
Hardware, BIOS, DOS, and other interrupts. You should not be without this file, which is widely-known as "Ralf Brown's Interrupt List". Ask about it. You will find

several times in 2001 and 2002, but when they did not materialize, portions of the new information on DOS and PC internals provided by Paul were circulated in preliminary form in the development community for peer-review and to assist in operating system development.
