About these units
CD (80 minute) (CD (80 min))
The 80-minute CD expanded storage to 700 MB, offering a modest but meaningful increase over the 74-minute version. This capacity became the industry standard for audio production, software, and media distribution. The slightly denser data-spacing required careful calibration but proved reliable for most computer and consumer hardware. For many users, CD-R and CD-RW discs became a primary means of personal backups, music burning, and long-term storage before USB drives became widespread.
MAPM-Word (MAPM-word)
A MAPM-word refers to a word-size unit used in certain legacy mainframe and specialized computing systems; MAPM architectures often used 36-bit or 48-bit word sizes, enabling high-precision arithmetic and scientific calculation. These larger word widths were crucial before floating-point standards matured, giving scientists more numerical accuracy in simulations, engineering computations, and cryptographic calculations. Although modern systems have largely standardized on 32- and 64-bit words, MAPM-word units reflect computing's experimental phase, when designers tailored architectures to unique scientific, military, or industrial needs. Understanding such units is essential for interpreting old software, data formats, and archival system documentation.
