- 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.
- Voyager 1 (Wikipedia)
Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and the interstellar space beyond the Sun’s heliosphere. It was launched 16 days after its twin, Voyager 2. It communicates through the NASA Deep Space Network (DSN) to receive routine commands and to transmit data to Earth. Real-time distance and velocity data are provided by NASA and JPL. At a distance of 163.1 AU (24.4 billion km; 15.2 billion mi) from Earth as of June 2024, it is the most distant human-made object from Earth. The probe made flybys of Jupiter, Saturn, and Saturn’s largest moon, Titan. NASA had a choice of either doing a Pluto or Titan flyby; exploration of the moon took priority because it was known to have a substantial atmosphere. Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons.
- 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.
- 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.
