In the interest of providing direct access to my personal MVS38J community software contributions, I wanted to offer real-time access to my software functions to facilitate a ‘test drive’ experience for potential and interested community members before downloading and installing my packaged software onto your system.
Therefore, a minimal capacity demonstration system comprised of the public domain operating system MVS38J TK4- version 8 from Jürgen Winkelmann along with the ISPF product from Wally Mclaughlin.
Additionally, TK5 system from Rob Prins is available for public access hosting some my personal community software.
