microcomputer, designed by Jonathan Titus, using the Intel 8008.
- Creative Computing, the first magazine for home computerists, is founded.
- Hal Singer starts the Micro-8 Newsletter for enthusiasts of the Mark-8.
- Bravo is developed for the Xerox Alto computer. It is the first WYSIWYG
program for a personal computer.
- Despite being US$300,000 in debt, Ed Roberts is able to borrow an additional
US$65,000 from the bank to complete work on what would be the Altair.
- Hal Chamberlin and others begin publishing The Computer Hobbyist magazine.
- Scelbi sells its last Scelbi-8H, discontinuing hardware to concentrate
- Popular Electronics publishes an article by MITS announcing the Altair
8800 computer for US$439 in kit form. It uses the Intel 8080 processor.
The Altair pictured on the cover of the magazine is actually a mock-up,
as an actual computer was not available.
- Les Solomon, publisher of Popular Electronics, receives Altair number
- (spring) In a desperate act to save his failing calculator company,
MITS company owner Ed Roberts begins building a small computer based on
Intel's new 8080 chip, with plans to sell it for the unheard of price

US$180, and ASCII keyboard kit for US$40.
- Gary Kildall, of Microcomputer Applications Associates, develops the
CP/M operating system for Intel 8080-based systems.
- Motorola introduces its 6800 chip, an early 8-bit microprocessor used
in microcomputers and industrial and automotive control devices. The 6800
was designed by Chuck Peddle and Charlie Melear.
- Brian Kernighan and Dennis Ritchie develop the C programming language.
- RCA releases the 1802 processor, running at a blazing 6.4 MHz. It is
considered one of the first RISC chips. It is used on a variety of devices,
from video games to NASA space probes.

- Railway Express loses Ed Robert's only prototype Altair computer, en
route to New York for review and photography for publishing by Popular
- (1975?) IBM scientist John Cocke completes a prototype high-reliability,
low-maintenance computer called the ServiceFree. It incorporates a RISC
architecture, achieving at least 80 MIPS, 50 times faster than IBM's fastest
mainframe at the time. However, the project is later canceled due to the
massive "Future Systems" project consuming much of IBM's resources.
