------- This list was compiled over several months time and spans many areas of interest (from telco terms to general/common computer terms). Multiple sources were used, including: a list from Metal Shop Private BBS (as published in Phrack), a list from PIMP issue #3, text files on specific networks, various telco documents (Bell, AT&T, MCI) I've found and read, my own knowledge, and from memory, etc. It isn't a complete list by any means, but it's as complete as it's ever going to be. So, that's why I decided that I might as well release it the way it is. It was originally released at the end of 1998 in issue #13 of the Damage, INC. Newsletter. A few additions and minor changes have been made to it since then. I may decide to update it and release a new version sometime in the distant future. That is, if I have the time to type all of the acronyms and definitions from various documents that I've obtained. Gathering together masses of loose papers that are strewn around is an undertaking in itself. Final Notes: ----------- Hopefully you find this small list of acronyms useful. It was created to be used mainly as a reference for terms that you might run across while exploring systems, reading text files, looking through documents you found while trashing or whatever. :)ÿÿÿÿ - THC Phreak ú Damage, INC. damage_inc@disinfo.net http://surf.to/damage_inc
