Getting MVS 3.8j Turnkey TK4-

In the early 1960s and 1970s for various reasons IBM did not copyright their MVS Operating System and Languages. Due to the efforts of Volker Bandke, MVS 3.8j was made available to to run on the Hercules mainframe emaulator created through the efforts of Jay Maynard and others. More recently Jürgen Winkelmann modified the Turnkey 3 system with a number of improvements and released it as Turnkey 4-. As a result you can now run a mainframe operating system on Windows, Linux, and Mac computers. I even have it running on a Raspberry PI 3. This page explains how to get and install Tur(n)key MVS 3.8j 4-.

The distribution for MVS 3.8j can be found at this link.

Towards the bottom of this page you want to download the tk4-_v1.00_current.zip link. Once that link has been downloaded you will want to unzip it in the directory where you will run the application from. I recommend using the directory "mainframe" or "tk4-mvs".
