Welcome to the COREDUMP.COM historical site. This domain was established in the Summer of 1985 during the pre-Internet era and before Networks Solution Inc. got a mandate from IANA to rip us off and charge money for domain name registration.
The early verision of our hardware was an AMD-powered 386 prototype board running at a clock frquency of 5 MHz with mimimal version of the BSD386 operating system. Eventually, this hardware was converted to a stand-alone floppy-based router and served in this function for the next 10 years. Computer communication was limited those days mostly to email and Usenet interest-based group discussions. Occasionally we used Telnet to help each other solve technical problems, remotely. These were the days when trust and cooperation served as the basis for advancing the art and engineering of computing and would lead to advancements that exceeded our wildest imagination, at the time.
In 1986 I started working at the National Semiconductors Portland Development Center (PDC) as a senior systems developer. Consequently, the next hardware powering this site was upgraded to a one-of a kind prototype of a 32-bit computer, using a National Semiconductor Corp. NS-32032 as the application processor and NS-32016 as the I/O processor. The hardware code name was "ORCA". I made custom modifications to the board and overclocked the main processor to a whooping 13.56 MHz :) (up from the nominal frequency of 10 MHz). I actually used a crystal meant to be used for CB Channel-5 to control the frequency of the system main clock generator. Consequently, the computer node name became channel-5.coredump.com... The operating system used by this "beefy" new system was Genix, a customized version of Bell Labs UNIX System 5 Verions 4, otherwise known as SVR4. Communication with other participating computing nodes was achieved using dial-up lines with telephone-based modems. Due to our proximity to the Portland, Oregon metropolitan area the volunteer-operated network became known as RAIN.NET
Without a doubt, the person that we all owe thanks for in facilitating our volunteer based computer network is Alan Batie. Alan volunteered to provide a stable base in Portland, Oregon that would serve as a communication hub for the rest of us, computer hackers. See Alan's web site at: https://alan.batie.org/.
