CP/M

documentation

Tim Olmstead Memorial Digital Research CP/M Library (cpm.z80.de) Here, in one place, are all the manuals we have for Digital Research software products. These manuals have been produced by scanning, and ocr’ing, the originals. Where possible, the look and feel of the original has been preserved as much as possible. The manuals presented here have been through an extensive clean-up process. OCR is not an exact art, at least not in the affordable software available for the PC, so a separate cleanup process is necessary to produce a pretty manual.

Charles Manson (Wikipedia) Charles “Charlie” Milles Manson (né Maddox; November 12, 1934 – November 19, 2017) was an American criminal, cult leader and musician who led the Manson Family, a cult based in California, in the late 1960s. Some of the members committed a series of at least nine murders at four locations in July and August 1969. In 1971, Manson was convicted of first-degree murder and conspiracy to commit murder for the deaths of seven people, including the film actress Sharon Tate. The prosecution contended that, while Manson never directly ordered the murders, his ideology constituted an overt act of conspiracy.

Digital Research Source Code (cpm.z80.de) Here you will find all the source code that we have for Digital Research software products. If there is something that you don’t see the source for, and you have it, please drop me a line, and I will provide you an address where to send it. It will then be posted here so everybody can enjoy it.

Why are there both TMP and TEMP environment variables, and which one is right? (devblogs.microsoft.com) If you snoop around your environment variables, you may notice that there are two variables that propose to specify the location of temporary files. There is one called TMP and another called TEMP. Why two? And if they disagree, then who’s right?

CP/M (Wikipedia) CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors.
