Please note that this is an old mirror of the original Unofficial CP/M archive. The current and actively maintained site is located at http://www.cpm.z80.de/
This site will be a clearing house for CP/M software. That's the good news. Now the bad news. What original source you will find on this site is all there is! The rest has been lost to the ages for one reason or another.
This site is user supported. That means that much (most) of the software posted here was donated by various individuals. The postings on this site are not yet complete. It is the goal of this site to be able to post every operating system, compiler, and utility that Digital Research produced for the 8080, Z80, Z8000, and 68000 processors (assuming we can find it).
This site is dedicated to the early days of microcomputing. Digital Research produced operating systems, utilities, and language products for early microporcessor systems. These systems included such microprocessors as the 8080, Z80, 68000, Z8001, and 8086/8088. The workhorse of the operating system for these systems was CP/M. A more advanced operating system, MP/M, allowed multi-tasking and multi-user, systems to be built.
You will find manuals for many of the Digital Research software products here. They are mostly in Postscript format
Get the binary for Digital Research software here.
What source code we have is here.
A more advanced operating system was produced as an extension to the PC-DOS operating system that ran on the IBM PC/XT. This system was called GEM. GEM has now been released under the GNU Public Lisence, so the restristions on CP/M products do not apply.
GEMDOS is a companion OS product to GEM, but it runs on 680x0 systems; primarily the ATARI ST, and the LISA.
