20th Century: 1971

DND beginnings. Let us discuss this book. By Source (WP: NFCC#4), Fair use.

Gygax and Perren’s set of medieval miniatures rules from the Castle & Crusade Society newsletter The Domesday Book brought Gygax to the attention of Guidon Games, who hired him to produce a “Wargaming with Miniatures” series of games. Towards the end of 1970, Gygax worked with Don Lowry to develop the first three products for the new Guidon Games wargames line. Among the three was a pamphlet of medieval rules entitled Chainmail which adopted much of the medieval rules published in the Domesday Book. Late in the development process, Gygax added to the end of Chainmail fourteen pages of a “Fantasy Supplement” which detailed the behavior of Heroes, Wizards, dragons, elves, and various other fantastic creatures and people.

The first edition Chainmail saw print in March 1971. It quickly became Guidon Games’ biggest hit, selling one hundred copies per month. A second edition would follow in July 1972, with several expansions and revisions to the original game. The January 1972 issue of the International Wargamer initially published the most significant of these changes, including the splitting of the “Wizard” type into four distinct levels of spell casters.

IBM shipped the first units of Noble’s solution, the 23 FD “Minnow” in 1971. The 8-inch floppy disk drive with removable read-only, flexible “memory disks” offered a storage capacity of 80 kilobytes (KB), approximately 3,000 punched cards.

While at Intel, Dov Frohman invented and patented (#3,660,819) the EPROM in 1971.

20th Century: 1970

The Unix time, aka Epoch time, is set to start on January 1, 1970.

The Network Control Program (NCP) provided the middle layers of the protocol stack running on host computers of the ARPANET, the predecessor to the modern Internet.

NCP preceded the Transmission Control Protocol (TCP) is a transport layer protocol used during the early ARPANET. NCP was a simplex protocol that utilized two port addresses, establishing two connections for two-way communications. An odd and an even port were reserved for each application layer application or protocol. The standardization of TCP and UDP reduced the need for the use of two simplex ports for each application down to one duplex port. Stephen D. Crocker, then a graduate student at UCLA, formed and led the Network Working Group (NWG) and specifically led the development of NCP. Other participants in the NWG developed application-level protocols such as TELNET, FTP, SMTP, among others.

Intel released its first commercially available DRAM, the Intel 1103 in October 1970. Capable of storing 1024 bytes or 1 KB of memory.

The Intel 4004, developed in 1970, is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first commercially produced microprocessor and the first in a long line of Intel CPUs.

On the 13th of April, after docking with the Lunar Module, the astronauts, Jim Lovell, Fred Haise, and Jack Swigert, discovered that their oxygen tanks had ruptured and ended up entering and returning to Earth in the Lunar Module instead of the Command Module. There is footage of inside module and Mission Control shots, personal commentary by the astronauts concerning the problems as they developed, national news footage and commentary, and a post-flight Presidential Address by President Richard Nixon.


20th Century: 1969

Spacewar is a two-player networked game inspired by the original Spacewar! on PLATO. Two players control a spaceship each in a two-dimensional representation of space. The ships can thrust, rotate, and fire and must try to destroy each other. The ships are represented by custom ASCII graphics. Unlike the original Spacewar! Here ships have only limited fuel and hyperspace jumps. Connected users are listed on-screen (big board) and can be challenged to a duel. The game was originally written for PLATO III but later ported to PLATO IV. When PLATO went on the ARPANET in 1974 the game became incompatible. It was replaced by Orbit War.

The first Request for Comments, RFC 1 published. The RFCs (network working group, Request For Comment) are a series of papers that are used to develop and define protocols for networking; originally the basis for ARPANET.


Telnet is an application protocol used on the Internet or local area network to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).

Telnet was developed on September 25, 1969 beginning with RFC 15, extended in RFC 855, and standardized as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the first Internet standards. The name stands for “teletype network”. Historically, Telnet provided access to a command-line interface on a remote host.
