The HPE NonStop community, historically rooted in Tandem Computers’ culture of openness, has held an annual gathering since the early 1980s.
Originally known as the International Tandem Users Group (ITUG) summits, the main conference evolved into the NonStop Technical Boot Camp (TBC), now organized by Connect Worldwide and heavily supported by Hewlett Packard Enterprise.
The conference serves as the premier annual gathering for NonStop users, focusing on technical education, mission-critical applications, and networking.

The AI & 50th Anniversary Era (2020–2026)
Conference Insights and Evolution
NonStop TBC 2026 is scheduled for Sept 14–18 in Orlando, FL.
The history of Tandem Computers (now HPE NonStop) conferences is a nearly 50-year chronicle of community-driven knowledge sharing, evolving from the Tandem User’s Group (TUG) in 1978 to the modern HPE NonStop Technology & Business Conference (TBC).
These events have served as the primary venue for sharing best practices on fault tolerance, high availability, and mission-critical application design, bridging the gap between Tandem’s founding in 1974 and HPE’s current virtualized NonStop systems.

BASE24 is a foundational electronic payments software suite developed by ACI Worldwide, first launched in 1982 to provide “always-on” (24/7/365) transaction processing, primarily on HP NonStop servers.
It is used by large financial institutions to acquire, authenticate, route, switch, and authorize card- and non-card-based financial transactions across multiple channels, including ATMs, point-of-sale (POS) terminals, and mobile/internet banking.
The product has evolved from “Base24 Classic” into BASE24-eps (formerly BASE24-es), a modern, object-oriented, platform-independent payments engine designed to support high-volume, real-time transaction processing in hybrid or cloud-based environments.

HP Connect (often referred to as Connect Worldwide) is a leading global IT user community dedicated to professionals using Hewlett Packard Enterprise (HPE) and HP Inc. solutions. It serves as an independent hub for peer-to-peer networking, technical education, and advocacy, primarily supporting users of high-availability systems like NonStop, ProLiant, and HP-UX.
Historical Timeline by Era
The community’s history is defined by the evolution and eventual merger of several legacy user groups representing the giants of the mid-20th-century computing world.
1. The Legacy Foundations (1960s – 1990s)
Before the name “Connect” existed, three distinct user groups served the customers of the companies that would eventually form the modern HP/HPE ecosystem:
2. The Consolidation Era (2000 – 2008)
Major corporate mergers necessitated the union of these independent communities:
3. The Unified “Connect” Era (2008 – 2015)
During this period, Connect Worldwide solidified its role as the primary independent voice for HP enterprise technology:
4. The Modern Era & Digital Transformation (2015 – Present)
Following the historic 2015 split of Hewlett-Packard into HP Inc. and Hewlett Packard Enterprise (HPE), the community adapted to a dual-focus landscape:
The European BASE24 User Group (EBUG) was a prominent, community-led organization dedicated to the BASE24 payment processing system. It served as a vital hub for financial institutions and vendors to exchange technical knowledge, discuss platform migrations, and influence the development of ACI Worldwide products.

Tandem Computers, founded in 1974 by James (Jimmy) Treybig, revolutionized the computing industry by pioneering fault-tolerant computer systems. Designed specifically for online transaction processing (OLTP) in banking, stock exchanges, and telephone switching, Tandem’s “NonStop” systems provided near-zero downtime by utilizing redundant, modular processors and a “shared-nothing” architecture.
Tandem remained an independent, rapidly growing company until it was acquired by Compaq in 1997, later becoming part of Hewlett Packard Enterprise (HPE).

sp/ARCHITECT was a pioneering electronic banking and funds-transfer software suite originally developed by the Runcorn-based firm The Software Partnership (TSP). Following its acquisition by the American firm Deluxe Electronic Payment Systems in 1994, the Runcorn office became the European hub for what was then rebranded as Deluxe Data.

Overview
The Runcorn operation specialised in high-availability, mission-critical banking software, specifically the sp/ARCHITECT-BANK product. This software was designed to run on Tandem Computers (now HPE NonStop), which were known for their fault-tolerant architecture. The “sp/ARCHITECT” platform was highly valued for its client-server design, allowing it to be adapted for various hardware brands, including Unix-based systems.

The HPE NonStop architecture is defined by its “shared-nothing” design, where every hardware and software component is redundant and operates independently to ensure 100% operational continuity. For over 40 years, it has evolved through four distinct hardware eras while maintaining upward software compatibility.
1. The Tandem Era (1974–1997): Proprietary Foundations
2. The MIPS Era (1991–2004): Migration to RISC
3. The Itanium Era (2005–2013): HP Integrity NonStop
4. The Modern HPE Era (2014–Present): x86-64 & Virtualization

Tandem TAL (Transaction Application Language) is a block-structured, procedural language designed in the mid-1970s for Tandem’s NonStop fault-tolerant operating systems, optimized for systems programming, high-reliability OLTP, and direct hardware interaction. It is heavily influenced by ALGOL and HP 3000 systems, allowing high-performance, message-based applications, and remains supported on modern HP Enterprise NonStop x86-64 platforms.

PTAL Overview and Timeline
Tandem PTAL (Portable Transaction Application Language) is a block-structured, procedural systems programming language used on HPE NonStop (formerly Tandem) servers. It is the portable successor to the original TAL (Transaction Application Language), designed to allow high-level systems programming without an assembler while maintaining near-machine efficiency.
Overview: TAL, PTAL, and epTAL
The language evolved to support different processor architectures over Tandem’s 50-year history:
Historical Timeline by Year
Year Milestone
1974, Tandem Computers founded by James Treybig; initial design of the Tandem/16 hardware begins.
1976, TAL released. The Tandem/16 (NonStop I) ships with TAL as its only programming language.
1981, NonStop II introduced, adding 32-bit addressing support to TAL via an “extended data segment”.
1983, NonStop TXP launched; first major reimplementation of the instruction set architecture supported by TAL.
1986, NonStop VLX introduced with 32-bit data paths; NonStop SQL released, often managed via TAL-based systems.
1989, NonStop Cyclone released, the high-end mainframe competitor for the TAL environment.
1991, PTAL Development starts with the release of Cyclone/R, the first MIPS-based machine. TAL code is initially translated via an “Accelerator” tool before native PTAL compilers take over.
1993, Himalaya K-series released; native mode operating system (NSK) and native compilers (PTAL) become standard.
1997, Compaq acquires Tandem. Migration begins from MIPS to Alpha (later abandoned).
2002, HP merges with Compaq. Development focuses on the Itanium (TNS/E) architecture.
2005, epTAL introduced for the new Integrity NonStop i servers based on Intel Itanium microprocessors.
2014, x86 Migration. NonStop X (TNS/X) systems are released, transitioning the TAL/PTAL environment to Intel x86-64 processors.
