The CCP took user commands and either executed them directly internal commands such as DIR to show a directory or ERA to delete a file or loaded and started an executable file of the given name transient commands such as PIP.ĬOM to show various file and system information. It contained functions such as character input and output and the reading and writing of disk sectors. The transient commands resided in files with the extension. Motorola handheld scanner connect to wifiĪ number of transient commands for standard utilities were also provided. WordStar used the 8th bit as an end-of-word marker.
The other characters made possible by the 8-bit byte were not standardized.įor example, one Kaypro used them for Greek characters, and Osborne machines used the 8th bit set to indicate an underlined character. I had picked up a Z80 assembler named "zmac" from the Internet quite some time ago.This computer platform was widely used in business through the late s and into the mids.

They do little useful error checking, but it should be pretty obvious from the code how they work. The code names the virtual hard-drives as "? Their contents should be identical to the real thing, even down to the reserved tracks, assuming I did it right.Īll these files are also in "A-Hdrive", all assembled and ready to run. The floppies are the traditional 8" k drives. The hard disks emulated are the venerable ST 5Mb 5" 5Mb drives. Emu8080: an HTML5 App to Emulate a Complete CP/M MachineĮnter '? The file "z Most variables are accessed via macros defined in "defs. They're pretty generic and ought to work under just about anything. The file "Makefile" will need tweaking for your system. It should be quite easy to port to other UNIX-line systems. This is not the fastest emulator around, but it's very portable. It currently supports two image formats and automatically detects the correct format. COM file located in the current directory. The BDOS emulation can be optionally disabled.

Here's a Web page with a MB copy of Don Maslin's files, which include Teledisk images of many vintage system disks.Īfter he passed, his archives spread to several Web archive sites. Don Maslin passed away on Sept 10 There was discussion in comp. I describe some of those archives on my S Web links page. I have some links here to the sites I've mentioned here. Of course, your computer has to have one of the processors listed. The notes below discuss this option and what that means. Check Dave Dunfield's archive as discussed below. If you want to compare them, download the docs and software and go right ahead! Linux" or " Mac" for more information.
Frankly, a Web search or the links on this page will lead to plenty of information. Later OS's from DRI had additional layers of software and supported much more hardware and OS features: you'll have to read the docs for specifics! There is no simple answer to these questions. The CCP is the command-line processor with simple features like "dir", "type", and so forth. BDOS is the core of the operating system, responding to system calls from running programs. More information is on my Digital Research Web page, and other pages on my Web site. I worked on that through and updated my notes since. I decided then to describe that history on my Web site, before it was lost. To learn more about S check my S home page.
