- 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.
- 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-86 (Wikipedia)
CP/M-86 is a discontinued version of the CP/M operating system that Digital Research (DR) made for the Intel 8086 and Intel 8088. The system commands are the same as in CP/M-80. Executable files used the relocatable .CMD file format.[nb 1] Digital Research also produced a multi-user multitasking operating system compatible with CP/M-86, MP/M-86, which later evolved into Concurrent CP/M-86. When an emulator was added to provide PC DOS compatibility, the system was renamed Concurrent DOS, which later became Multiuser DOS, of which REAL/32 is the latest incarnation. The FlexOS, DOS Plus, and DR DOS families of operating systems started as derivations of Concurrent DOS as well.
