The following versions exists:-
VM/370 Community Edition
This is the newest version of VM/370. It includes the lastest changes from the Sixpack editions plus improved support for the BREXX Interpretor. Download from ?
Robert O'Hara's Six Pack
This is a newer version of the VM/370R6 Public Domain system. It has a more up-to-date GCC with a choice of run-time libraries and extra Editor modifications to allow editing multiple files.
Paul Gorinskey's 5-Pack System
This is the version that I use every day. It has all Andy's fixes plus many enhancements that make it an almost useable system.
Andy Norrie's 4-Pack system
This system is probably the most consistent system available. Andy put a lot of effort into re-working and cross checking the patch's but it lacks many of the enhancements of Paul's system.
Bob Abele's Original 3-Pack System
This is Bob Abele's original distribution. Unlike the systems above which are distributed as “ready to IPL” DASD, this system is distributed as AWS takes that need to be restored to 3330 packs.
