HB1VAX (OpenVMS BBS)

HB1VAX is based on a Alpha server DS10 with OpenVMS. I have been a VMS specialist for many years (1992-2017). In 1989 we got our first MicroVAX 3600 and in 1992 we got three MicroVax 3100 systems. Main function of the systems was supporting the logistics (WMS) and operational [MES] executie processes. After supporting the VAX systems for many years we replaced the systems for a AlphaServer cluster environment that was build on two AlphaServers DS20 in 2000. In 2017 we ported the last of the applications running on the VMS cluster to a new MES and WMS system. Finaly i put the cluster down after running for 17 years 24/7 on march the 24, 2017. The end of a era.... I never lost intressed in the good old Digital systems. Nowadays i still have a AlphaServer DS10 running (HB1VAX). Besides the operationl system i have a collection of old Digitall machines and hardware like a VAX3600, VAX3100, VAX-I, VAX-II, PDP-11, VXT2000, VXT420, VXT520 and the AphaServer DS10.

Application Services

HB1VAX OpenVMS Alpha server DS10 is running various services and a home made BBS. HB1VAX can be connected through the HB9NOS node (just type VAX at the prompt) The BBS "software" is made in DCL (Digitall Command  language) and will give you acces to a personal mailbox and download area. I'm just playing arround with the code to make something usefull. I am still working and searching to get AX25 working on a OpenVMS platform, if anyone can help i will appreciate it! 


What is OpenVMS? 

OpenVMS is a multi-user, multiprocessing virtual memory-based operating system (OS) designed for use in time-sharing, batch processing, and transaction processing. It was first released by Digital Equipment Corporation in 1977 as VAX/VMS for its series of VAX minicomputers. OpenVMS also runs on DEC Alpha systems and the HP Itanium-based families of computers. OpenVMS is a proprietary operating system, but source code listings are available for purchase.

The name VMS is derived from virtual memory system, for one of its principal architectural features. When process priorities are suitably adjusted, it may approach real-time operating system characteristics. The system offers high availability through clustering and the ability to distribute the system over multiple physical machines. This allows the system to be tolerant against disasters that may disable individual data-processing facilities.

OpenVMS contains a graphical user interface (GUI), a feature that was not available in earlier original VAX/VMS releases. Prior to the introduction of DEC VAXstation systems in the 1980s, the operating system was used and managed from text-based terminals, such as the VT100, which provide serial data communications and screen-oriented display features. Versions of VMS running on DEC Alpha workstations in the 1990s supported OpenGL[8] and Accelerated Graphics Port (AGP) graphics adapters.

Enterprise-class environments typically select and use OpenVMS for various purposes including mail servers, network services, manufacturing or transportation control and monitoring, critical applications and databases, and particularly environments where system uptime and data access is critical. System up-times of more than 10 years have been reported, and features such as rolling upgrades and clustering allow clustered applications and data to remain continuously accessible while operating system software and hardware maintenance and upgrades are performed, or when a whole data center is destroyed. Customers using OpenVMS include banks and financial services, hospitals and healthcare, network information services, and large-scale industrial manufacturers of various products.

Origin and History

In April 1975, Digital Equipment Corporation embarked on a hardware project, code named Star, to design a 32-bit virtual address extension to its PDP-11 computer line. A companion software project, code named Starlet, was started in June 1975 to develop a totally new operating system, based on RSX-11M, for the Star family of processors. These two projects were tightly integrated from the beginning. Gordon Bell was the VP lead on the VAX hardware and its architecture. Roger Gourd was the project lead for the Starlet program, with software engineers Dave Cutler (who would later lead development of Microsoft's Windows NT), Dick Hustvedt, and Peter Lipman acting as the technical project leaders, each having responsibility for a different area of the operating system. The Star and Starlet projects culminated in the VAX 11/780 computer and the VAX-11/VMS operating system. The Starlet name survived in VMS as a name of several of the main system libraries, including STARLET.OLB and STARLET.MLB.

Over the years the name of the product has changed. In 1980 it was renamed, with version 2.0 release, to VAX/VMS (at the same time as the VAX-11 computer was renamed to simply VAX). With the introduction of the MicroVAX range such as the MicroVAX I, MicroVAX II and MicroVAX 2000 in the mid-to-late 1980s, DIGITAL released MicroVMS versions specifically targeted for these platforms which had much more limited memory and disk capacity; e.g. the smallest MicroVAX 2000 had a 40MB RD32 hard disk and a maximum of 6MB of RAM, and its CPU had to emulate some of the VAX floating point instructions in software. MicroVMS kits were released for VAX/VMS 4.4 to 4.7 on TK50 tapes and RX50 floppy disks, but discontinued with VAX/VMS 5.0.

In 1991, VMS was renamed to OpenVMS as an indication for its support of "open systems" industry standards such as POSIX and Unix compatibility, and to drop the hardware connection as the port to DIGITAL's 64-bit Alpha RISC processor was in process. The OpenVMS name first appeared after the version 5.4-2 release.
