This domain was established in the Summer of 1985 during the pre-Internet era and before Networks Solution Inc. received their mandate from IANA to rip us off by charging money for domain name registration. The domain name was inspired by term coredump, a procedure that was frequently used by computer programmers to debug computer software behavior, off-line, before much more effective, on-line diagnostic tools were developed and deployed.

The early version of computer hardware that we used on this Internet Node was powered by an 80386 CPU manufactured by AMD. The motherboard was an early prototype with the CPU running at a clock frequency of measly 5 MHz. On top of this hardware we managed to trim the software to the minimum necessary to execute a very slim version of the BSD386 operating system. Eventually, this hardware was adapted to become a dedicated, stand-alone, floppy-disk based IP Edge Router (gateway), appropriately named GATEWAY.COREDUMP.COM. Amazingly, this piece of computer hardware served as our network gateway, over the next 10 years, non-stop around the clock (24/7),with very few service interruptions. Try to beat this record with any of today's electronic products...
Computer payload traffic in the 1980's was rather limited in content types. Most traffic consisted of email and Usenet interest-based group discussions. Occasionally we used Telnet to help each other solve technical problems, remotely. Those were the days when trust and cooperation served as the basis for advancing the art and engineering of computing. What drove most of us was the sense of community and the spirit of participating in a shared goal that exceeded what each of us could achieve on our own. This collaboration would eventually lead to technological advancements that exceeded our wildest expectations.
In 1986 I started working at the National Semiconductors Portland Development Center (PDC) as a senior systems developer. Consequently, the next hardware powering COREDUMP.COM became a one-of a kind engineering 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 operating system used by this "beefy" new system was Genix, a customized version of Bell Labs UNIX System 5 Version 4, otherwise known as SVR4 that was ported to run on NS32 hardware.

Without a doubt, the person that we all owe thanks for in facilitating our volunteer based computer network in later years, 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.
