Cp/m emulator windows

And of course, some kind soul has uploaded it to archive. Later models used an ASIC to handle part of the video subsystem. It was perhaps the most emulated system of all time.

And the first real, portable OS for microcomputer, too. Very helpful in getting WordStar files off the Xerox disks. When I first saw the picture I thought they had built the computer into the floppy drive and I thought, what a great idea! Using the cursor keys will result sooner or later in a random behaviour, if a program which uses control sequences for a full screen display, like WordStar, is used.

Programs with direct disk access do not work. Please be kind and respectful to help make the comments section excellent. Comment Policy. This site uses Akismet to reduce spam.

The program was released into the public domain, or was going to be. It is now a bit Windows executable so it should run on any bit or bit Windows computer. For those of you that are only familiar with a Windows environment, it may be a shock as it uses console mode.

Prompts will appear on the screen and you press keys in response. The original processed keys as you pressed them. All credit for the program goes to the original author see the source code. There are also emulators around for CPUs and systems. I have two main Z80 emulators.

These are z80emu, a HTML5 one that runs in your browser; and z80sim, a Windows program that runs on your desktop. It just runs. Which are the right letters and which are in the right spots? The notes below discuss this option and what that means. Of course, your computer has to have one of the processors listed. I have some links here to the sites I've mentioned here. I describe some of those archives on my S Web links page. Don Maslin passed away on Sept 10 There was discussion in comp.

But in , Al Kossow of bitsavers. Here's a Web page with a MB copy of Don Maslin's files, which include Teledisk images of many vintage system disks. After he passed, his archives spread to several Web archive sites. In , I found that Al Kossow's "bitsavers. A Google search string ".

IMG files. Other disk images there include. TD0 Teledisk format and. IMG not photos but disk bit images from versions of Catweasel. See my note above about Catweasel and other formats for details. Over time, the megasite "classcmp. Sites not copied, are at least linked to from there.

Jon says Dave apparently is not updating his list. Meanwhile, in or , there were references in comp. In he moved much of that information to the linked "classiccmp" Web site from his own Web domain. Unfortunately, in Dave suffered serious injury and as a result has liquidated his vintage computers and it's impacted much of his activities. Details are on his Web site.

However, it's now more difficult to access his "imagedisk" files, and to contact him. I suggest you do a Web search for "dunfield imagedisk testfdc", to figure out the most-current and only links to his great imagedisk products. Consider a donation for his decades of service to the vintage computing community. Check his Web pages on the classiccmp site for all these activities. There's also versions of Teledisk there, and I believe Dave's utilities can handle Teledisk images too.

I discuss the Catweasel floppy controller product, and a variety of issues about diskette formats, on a technical Web page about diskette data recovery and copying. Here's what Dave had to say at in , about his work and where to access it, from a public post in comp. For backing up and restoring disks, as well as finding boot disks for known configurations, I urge people to check out the imaging tools and disk image archive on my [archive] site [now at classiccmp.

IMD files of disk] images of most soft-sector formats, including mixed density, odd sector numbering, differently formatter tracks etc. I have a page with details on how to connect 8" drives which work well in this configuration on a PC - this is my prime soft-sector disk manipulation tool. There are other transfer utilities for other systems available on that page as well. I'd like to ask that anyone with boot disks not already in the archive to please if you could, make images and send them to me for inclusion in the archive.

What I am trying to do is to build a shareable and archivable resource of boot disks, and the means to recreate them so that classic treasures won't have to sit idle waiting for the right disk to come along Go to the classiccmp site for Dave Dunfield's work. It ain't that easy. But, through the years, and even recently, some people have or are providing some of these capabilities.

There's some clues in the referenced discussion. Used Zcompatible computers are still available, decades after they were first sold and built. They are available from individuals, for sale or give-away; they are bought and sold on eBay and other general auction Web sites; and some Web sites for specific old computers also offer hardware for sale.

Check the Web, or personal for-sale Web sites, accordingly, there are too many venues to list. For example, the S systems I support to this day. There are companies which produce computer "hobby kits" of various sorts, but few of them are or Z80 based, and most don't support any kind of file storage device. But see my notes below. For example, consider the Heath Zenith H89 and H8.

He and others developed some new Heath H8 cards, similar or better than the original cards. I try to keep current Web pointers for these and similar Web sites, on my S Web pointers page. Lee Hart at sunris-ev. He has a tindie site for sales; he has other 8-bit computer project kits.

Web search will find many individual vintage-computing projects that come and go in the 21st century. Most of them use the very first sector on the first track as boot code. The hardware is able to read that boot sector and execute its contents. Some systems have sufficient hardware to read the system tracks directly without a boot sector. Smething has to load the "boot", and often that is a program in ROM called a "monitor", which runs when the computer is powered up.

So you may be able to format diskettes on a Windows or Linux system. The original DRI manuals with it tell you how to do this. The tools provided with it are sufficient to aid you in doing this. It is not impossible, just a challenge like many other challenges presented by older computers equipment. I also discussed his iCOM hardware and docs on this Web page. A number of people have provided me with source programs for a specific S floppy controller.
