The website = has an emulator and disk images for most of the user land and =E2=80=9CMDE= X=E2=80=9D -- a simple executive that John wrote to bootstrap his = software stack. This material survived in the hands of a few Powertran = Cortex enthusiasts. They also had disks for NOS/MT (binaries + sysgen), = but those were found after that website was made 10+ years ago. The Powertran Cortex design was also used to build an industrial control = computer, the PP95. The UK company behind that did most of the porting = work and had a complete M9900 system to do the work on. In 2018 the = inventory of that company was found in a garage including that M9900 = system. Also more disk images and manuals, including the NOS/MT User = Manual. The disks included a few that contained reconstituted (partial) = source code for NOS/MT. With a little help from John, I was able to = reconstitute the remainder of the source code. All this is not online. I will contact you off list to see how this can be best preserved. Paul
