_{Cover of the March 1977 issue of Byte}

Byte magazine (subtitled The Small Systems Journal) was a VERY early computer magazine with publication starting in 1975. This issue is from 1977. This is well before the IBM PC was introduced and there wasn't much in the way of what would come to be known as home or personal computers around. However, the Commodore PET, TRS-80 (Model I), and Apple II were all released year igniting what might be considered the first home computer war. Most other machines were either kit based (you build it yourself, often including soldering) or more business oriented (CP/M based machines). The main CPUs in use were the Intel 8080, Zilog Z80, and MOS 6502. This would remain true for several more years. The March 1977 issue of Byte includes:

Foreground

Simplified Omega Receiver Details - Byte tended to be pretty technical. The earlier the issue, the more technical it tended to be. This article just goes into building something called an Omega receiver. I guess if you didn't know what that was, you didn't need to build one. According to Wikipedia, "An Omega receiver is a device that picks up very low frequency radio signals transmitted by Omega stations to determine a position. It was used in conjunction with the Omega navigation system, which was operational from around 1971 until it was shut down in 1997. Omega receivers helped ships and aircraft establish their locations by receiving signals in the 10 to 14 kHz range from a network of eight fixed terrestrial radio beacons." Sort of an early GPS system...

Inexpensive Joystick Interfaces - Earlier computers wouldn't have joystick interfaces and there wasn't really a standard interface. Here's a guide for building your own.

Flights of Fancy with The Enterprise - A type-in BASIC action game based on Star Trek in which you must hunt down and destroy the Klingon battle cruisers. It requires approximately 22K of RAM which was a pretty hefty chunk in those days.

Give Your Micro Some Muscles - Using a computer to control external devices.

Review of the SWTPC PR-40 Alphanumeric Printer - An early dot matrix printer that looks more like a telegraph machine. It is a 5 by 7 dot matrix printer capable of printing the 64 upper case ASCII character set with 40 characters per line at a speed of 75 lines per minute. It comes in kit form, meaning you have to assemble it yourself, for $250.

Cassette Transports for the "Roll Your Own" Hobbyist - At this time, data storage for computer hobbyists was almost entirely done via cassette. Basically using the same cassettes and tape recorder devices you would use for audio. This article describes building your own cassette device starting with choosing a better transport mechanism than what you would typically find in cheap consumer devices.

The Digital Cassette Subsystem, Part 2 - The second part in a series on the technical details of using cassettes for computer storage.

Nucleus

PAPERBYTES Forum - Excerpts of various letters discussing machine readable printed software. Conceptually, this idea is similar to reading a barcode which was starting to become commonplace, for example, in supermarkets at this time. However, the idea here was to input entire programs via some kind of printed code.

BYTE Goes International - Byte announces new Australian edition of the magazine.

Letters - Letters from readers regarding arithmetic on the 8080, the ELIZA program, word processing on the Altair, cooling the CPU in an Altair 8800, bank switching with the RCA COSMAC 1802, and more.

A 6502 Op Code Table - A reference chart that includes all the op codes for the MOS 6502 CPU. Useful for debugging hex dumps.

What's New? - Phi Deck Tape Mass Storage for the Altair Bus (a tape drive for the Altair with up to 1 MB of storage), Computer Power & Light offers 8080A based computer system for $1863 completely assembled, new version of SC/MP processor from National Semiconductor, and more.
