The Software Partnership (TSP) was a highly specialized British software house based in Runcorn, Cheshire, that played a key role in early cutting-edge electronic banking software. The firm famously developed sp/ARCHITECT-BANK, an innovative enterprise banking system built explicitly for Tandem Computers (now HPE NonStop) fault-tolerant server systems. I was based there between 1990 and 1995.
The Software Partnership Logo
Below is a detailed overview of the company’s operational history, alongside the corresponding hardware/software architectural eras of the HPE NonStop platform it relied upon.
Detailed Overview
Core Focus: The Software Partnership specialized in online transaction processing (OLTP) and electronic automated banking software. Long before the internet became mainstream, TSP engineered early desktop access environments for corporate bookkeeping and inter-account bank transfers.
Key Product: Its flagship software suite, sp/ARCHITECT, ran on Tandem’s highly unique, redundant architecture. The software handled complex high-volume retail transactions, ATM networking, and ledger balances.
Major Clients: High-profile financial institutions deployed TSP’s systems, including TSB (Trustee Savings Bank), Bank of Scotland, Rabobank, and Denmark’s Girofon.
Legacy: TSP initiated a massive lineage of financial tech operations in the Runcorn/Warrington area. After subsequent buyouts and transitions, its corporate DNA integrated into modern banking giants, eventually operating under Fidelity National Information Services (FIS).
Detailed Timeline by Era and Year
The history of TSP mirrors the evolution of the underlying fault-tolerant architecture originally built by Tandem, later managed by Compaq, HP, and currently Hewlett Packard Enterprise (HPE).
Era 1: The Tandem Founding & TSP Inception (Mid-1970s – 1989)
This era is marked by Tandem’s creation of the fault-tolerant server market, which birthed the niche that TSP filled.
1974–1976: Tandem Computers is founded and ships its first 16-bit NonStop I (T/16) system, utilizing complete component redundancy to guarantee close to zero downtime for the financial industry.
1981: Tandem introduces the NonStop II, transitioning to battery-backed DRAM memory and enabling early 32-bit addressing.
Mid-1980s: The Software Partnership (TSP) is co-founded by Nigel Walsh. It establishes offices first in Timperley (Wingate Drive), then moves to Crowngate (Norton House) in Runcorn. The team begins developing online banking architectures explicitly for Tandem OS (Guardian) and early UNIX nodes.
1989: Tandem launches the NonStop Cyclone, a high-end mainframe system featuring superscalar CPUs and fiber-optic interconnects.
Era 2: The MIPS RISC Transition & Corporate Buyouts (1990 – 1999)
TSP reaches peak software deployment exactly as Tandem shifts its internal processor technology.
1990: TSP establishes itself as a major regional employment hub for software engineers following a massive boom in terminal banking technology. Software programmers deploy sp/ARCHITECT-BANK code for massive retail banks internationally.
1991: Tandem shifts its structural hardware away from proprietary chips, introducing its first MIPS RISC-based NonStop systems.
1992: TSP expands its Runcorn footprint, moving to custom facilities at Wingate House on Northway, Runcorn.
1994: TSP is acquired by American firm Deluxe Electronic Payment Systems (a division of Deluxe Corporation, one of the largest check printers and transaction processors in the US). The corporate name transitions to Deluxe Data.
1997: Due to shifts in the enterprise hardware landscape, Compaq Computer Corporation acquires Tandem Computers for $3 billion, taking over the NonStop lineage.
Era 3: The Itanium Migration & eFunds Realignment (2000 – 2013)
The architecture sheds its proprietary processors for industry standards, and TSP’s corporate legacy transforms.
2000: Deluxe Data’s electronic payment wing splits off and rebrands as EFD eFunds.
2001–2002: HP (Hewlett-Packard) merges with Compaq, absorbing the NonStop portfolio. Simultaneously, HP begins shifting NonStop servers from MIPS architectures to Intel Itanium processors.
2007: Following industry consolidation, the corporate remnants of the original TSP Runcorn operations are absorbed into Fidelity National Information Services (FIS) and relocated to Aegon House in Daresbury, Warrington.
Era 4: The Modern HPE NonStop X & Virtualization Era (2014 – Present)
The legacy of the high-availability software pioneered in Runcorn culminates in cloud and x86 integration.
2014: HP introduces NonStop X, completely migrating the underlying architecture to Intel x86-64 processors and implementing InfiniBand connectivity fabrics.
2015: Hewlett-Packard officially splits into two entities; the core mission-critical banking platform continues its five-decade lineage under Hewlett Packard Enterprise (HPE).

The official HPE Nonstop Technology Architecture is a specialized, 100% fault-tolerant infrastructure built with a tightly integrated hardware and software stack designed to eliminate any single point of failure. Formal instruction and architectural frameworks have been modernized under the newly relaunched HPE Nonstop Compute Training Portfolio curriculum.
Originally developed by Tandem Computers in 1976, the platform eventually became part of Hewlett Packard Enterprise (HPE). Unlike standard servers that can crash due to a single component failure, NonStop uses a tightly integrated, “shared-nothing” architecture to ensure that if a hardware or software component fails, another instantly takes over with zero downtime or data loss.
Core Architectural Features
To understand how HPE NonStop works, you need to understand its unique design principles:
Shared-Nothing Architecture: Every processor has its own dedicated memory, I/O channels, and copy of the operating system. No single component is shared, eliminating any single point of failure.
Process Pairs: Applications run using a primary process and a backup process on a different processor. The primary process constantly copies its state to the backup. If the primary fails, the backup immediately takes over.
Massive Scalability: Systems can scale up seamlessly from small distributed environments to massive clusters containing up to 24,000 processor cores without interrupting running operations.
Hardware Platform: The modern software environment runs on industry-standard x86 architectures, available as physical server racks (like the HPE NonStop NS9 X5) or as virtualized instances in hybrid cloud environments.
Dual Operating Environments
HPE NonStop runs a specialized operating system called NonStop OS. Inside this OS, developers and administrators interact with two distinct environments:
Guardian Environment: The native, proprietary environment optimized for high-volume Online Transaction Processing (OLTP). It handles tasks sequentially through process-oriented manually-started jobs rather than traditional automated queues.
Open System Services (OSS): A UNIX-like, POSIX-compliant environment built on top of the NonStop kernel. This allows organizations to run standard open-source applications, tools, and scripts natively alongside Guardian.
Ecosystem and Use Cases
HPE NonStop is rarely used for standard office automation or basic web hosting. Instead, it serves as the backbone for global industries where an hour of downtime could cost millions of dollars:
Financial Transactions: Powers global stock exchanges, automated teller machines (ATMs), and retail point-of-sale credit card processing, eg. BASE24.
Travel and Logistics: Runs critical airline reservation systems and real-time cargo routing infrastructure.
Database Management: Features its own highly secure, distributed database engine called NonStop SQL, which guarantees absolute data integrity across all transactions.
Modern Development: Supports traditional languages like COBOL85 and ANSI C, alongside modern DevOps integrations like Git, Ansible, and Eclipse-based IDE environments.
An architectural blueprint of an HPE NonStop environment typically separates the layout into three core interdependent layers:
Hardware & Fabric Layer: Consists of independent, loosely-coupled Processor Nodes (handling up to 24,000 cores globally) connected via an ultra-fast InfiniBand or ServerNet system fabric backbone.
I/O & Subsystem Layer: Utilizes Cluster I/O Protocols (CLIMs), splitting tasks between Storage CLIMs (SCLIMs) and Network CLIMs (NCLIMs) to isolate external communication from main processing.
Operating System & DB Layer: Runs the NonStop OS, which simultaneously manages the traditional Guardian environment, Open System Services (OSS) for UNIX/Linux paradigms, and the NonStop SQL distributed database engine.
