"In searching out the truth be ready for the unexpected, for it is difficult to find out and puzzling when you find it."

    --- Paraphrasing Heraclitus.

GBPPR 'Zine is the official technical journal of Green Bay Professional Packet Radio (GBPPR).  

Consider it a throw-back to the awesome hack/phreak 'zines like Phrack, TAP, X.25, ~el8, B4B0, BoW, PHANTASY, the LoD/H Technical Journals, Informatik, Frequency, PoC||GTFO etc., with a few surprises thrown in to keep it interesting...

In high school, between 1990 and 1994, I used to write a little hack/phreak 'zine called The Black Book (later changed to Cyber 'Zine, I'm not good with names...).  It mostly consisted of print-outs of information and files gathered from various BBSes and covered the local scene in Green Bay, Wisconsin, where not much happens, but has a surprising number of dedicated, hardcore hackers/phreaks - just check the news every once and awhile.  Anyway, the 'zine started out kinda lame with just me making and distributing it, then I started using the school's computers to save money on printer cartridges and paper and also started to get more people interested in helping.  There where a total of 14 issues (if I remember right) and a "staff" of about five people helping write articles and distribute.

Unfortunately, I don't have a lot of money, but I do have a lot of ideas!

GBPPR 'Zine is the latest самиздат incarnation and consists of information and ideas which I consider interesting to the hacker/maker/mad scientist community.  It is basically an attempt to re-energize the underground computer hacker community, while countering the lies and propaganda in $2600.

Note that I have very little interest in most "modern" technologies, as older hardware/software tends to be less expensive, easier to hack, and easier to understand...

The 'zine isn't very good, but I put WAY too much time and effort into yet, so enjoy.

(Note: Many of Bell System Practices and other telco-related documents have been re-scanned/OCRed and moved to a new webpage.  Also, many of the larger projects have been moved to their own webpages, as it's just easier to maintain, update, etc.)
