Version 3.7 is the latest one I can use on Windows XP; at least versions 3.10 to 3.12 cannot run on Windows XP (unless recompiled) and old versions are unavailable from the official website, because of this, please keep the mirror here on SourceForge alive, even if outdated.
"My pc thinks it's a MAINFRAME!". This is the mainframe, you still need an operating system like MVS or z/OS to run job's and applications like a true IBM mainframe. You can use the Hercules to learn mainframe assembler with z/Architecture Principles of Operation from IBM site. Not easy to a begginer to start using it. You will still need wc3270 to access zOS. Truly amazing stuff!
Fast and simple.
A nice emulator to get old (and new) large iron software (called mainframe software) running on a PC or Mac.
