A quarterly hacker zine created by Thomas Icom of IIRG (International Information Retrieval Guild), a group dating back to the Commodore 64 BBS days.
Cybertek has been known as Cybertek: The Cyberpunk Technical Journal, Cybertek Experimentors Journal (CEJ) and Cybertek Electric.
Cybertek has been published somewhat regularly in one form or another from the spring of 1990 untill at least 1998 and is likely the second oldest hacker zine (2600 being the oldest).
A typical issue is like a slightly lower tech version of 2600 with a healthy dose of survivalist paranoia thrown in. Cybertek seems to have dissapeared sometime in 1998.
