Howard's Seattle Computer Products SCP 86-DOS Resource Website

Some early 86-DOS Documentation is located on Tim Paterson's website.

86-DOS 1.0 has been successfully recovered from a copy of an 86-DOS 1.0 8" SSSD Floppy Disk provided by Robert J. Stevens.  The data on this disk was extracted using a CompuPro DISK1A controller, and a custom program to dump the raw sector data out to a serial port on a sector-by-sector basis.  It is available as a raw binary file, and as an ImageDisk (IMD) file.

86-DOS boots and runs on the SIMH/AltairZ80 Simulator.  The latest version (based on SIMH 3.8-0) is available from Peter Schorn's website:  Peter's site also includes 86-DOS and MS-DOS 1.25 disk images for use with the simulator.  The main SIMH website has more information on simulating other systems.

There is also a discussion of the 86-DOS recovery on the comp.os.cpm newsgroup.
