About these units
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.
Floppy Disk (5.25", DD) (floppy (5.25" DD))
The 5.25-inch DD floppy stored roughly 360 KB (IBM PC) or 1.2 MB (Apple II and others) depending on format. These flexible disks dominated early personal computing in the 1980s. They were physically fragile but offered an affordable way to distribute software, operating systems, and games. The vast majority of early PC software—from Lotus 1-2-3 to original DOS versions—shipped on 5.25" disks. Their shape and texture became symbols of the early PC revolution, despite their low reliability, susceptibility to dust, and limited capacity.
