Byte magazine was an American microcomputer magazine, influential in the late 1970s and throughout the 1980s because of its wide-ranging editorial coverage. Whereas many magazines from the mid-1980s had been dedicated to the MS-DOS (PC) platform or the Mac, mostly from a business or home user's perspective, Byte covered developments in the entire field of "small computers and software", and sometimes other computing fields such as supercomputers and high-reliability computing. Coverage was in-depth with much technical detail, rather than user-oriented. Print publication ceased in 1998 and online publication in 2013.

Treble boost. A very important point that's often overlooked is the tape quality . Bad tape means bad data. Use only fine grain premium tapes (Radio Shack Supertape is typical). The key thing to watch for is whether the amplitude variation is guaranteed to less than one decibel. If the variation isn't specified - don't use the tape. The cost difference between good and cheap tape is negligible. You should also always "certify" your tape before you use it by writing a repetitive and obvious.
On), and a fixed-size descriptor giving the address of the first character and the number of characters in the string. Fig. 4 illustrates descriptors for the statement label, instruction mnemon ic, and operand of a typical assembly language statement. Descriptors for character strings are handy for a number of purposes. Character string move and comparison routines can be written which take two descriptors as arguments. Output lines can be constructed from a sequence of descriptors, and error.
Described one method of hashing here; several other variations are possible . The most important of these is called "hashing with overflow chaining," in which all of the names which hash to the same starting address are chained together on a linked li st. This method, which is often used on large comput e rs with dyn amic storage allocation, is less suitab le for microcomputers because it requires an extra address field for each symbol table entry.

Will ultimately condense down into a set of bit busses. Integrated Circuits. This particular keyboard has a bunch of integrated circuits in the left hand portion of the encoder board. The photo illustrates arbitrary reference numbers U1 to U12 for the purposes of this article, since no references were buil t into the printed circuit board . Pul/up Resistors. In diode matrix boards, a set of negative logic "wired or" busses is used to generate each bit of the encoded binary word. One pullup.
