Great Mother of z/VSE ----> IBM 370 Mainframe OS on PC ----> myDOSVS:
Vintage IBM DOS/VS Rel 34
myDOSVS lets you run authentic IBM mainframe DOS-VS/POWER Rel 34 (from 1974) on your PC with ease. DOS/VS is z/VSE's great grandfather. myDOSVS is a Java program that provides an integrated environment in conjunction with the open source Hercules mainframe emulator providing a single window with several tabs for each major function that would normally require a separate program. This setup is suitable for hobbyist and students that want to compile and run COBOL, FORTRAN, PL/I, RPG, and System/370 assembler programs. VTAM is set up and ready to run, an example terminal application assembler source is provided along with an IBM 3279 emulation tab for your terminal. VSAM file access method is included. It also has the DITTO system utility program installed. It is not suitable for replacing a real mainframe with z/VSE however. It runs on Windows 7, 8, and the new Windows 10, and Linux. A series of screenshots can be seen here. Instructions are provided to install and boot the OS, submit your first job, start VTAM and run the example, and then shut it all down cleanly. Example compile jobs for COBOL, FORTRAN, PL/I, RPG, and Assembler are provided.
VBBlue3270 is a 3270 terminal emulator that can be used to connect to your VTAM programs as a normal user would in a mainframe shop. You can have your myDOSVS running in your basement computer room and connect to it with this terminal emulator from anywhere else in the house, or if you adjust your home router/firewall the internet as well.
As an additional perk, I now include the java VintageBBS telnet client on the CD. This allows you to connect to the over 300 bulletin board systems still operating in the US. The presentation has the same proportions as the old style PC monitors in use in that day. It includes a search feature to find the 5 closest BBS's to your specified ZIP code.
It comes on a CD setup and ready to boot, a 32 and 64 bit Hercules Windows installer, the Hercules source tarball for building on Linux, and the Java runtime environment installation package for Windows. For Linux the Java runtime would need to be downloaded from Oracle or installed from your repository.
