VIPER Issues
The VIPER was a newsletter published between 1978 and 1984 that was targeted toward hobbyists interested in RCA’s COSMAC VIP computer. Although it was first published by Terry Laudereau at Aresco, the newsletter was later printed by Ray Sills, founder of the VIP Hobby Computer Association (VIPHCA). The VIPER frequently contained articles by author Tom Swan. VIPHCA ceased publishing the VIPER in September of 1984.
