Research Machines Limited, Link Timeline History by Era and Device

Research Machines (now RM plc) has a long-standing history as a primary provider of technology for the UK education sector. Founded in 1973, the company transitioned from a hobbyist component supplier to a leading manufacturer of educational microcomputers and networking systems. 

Overview of Research Machines “LINK”

The LINK designation primarily referred to the RM Link 480Z, introduced in 1982. It was designed as a lower-cost, diskless network station that could “link” into a chain, typically using a more powerful 380Z as a file server. This system was one of three chosen for the UK government’s 1982 Educational Scheme. 

Timeline History by Era and Device

The Founding Era (1973–1976)

  • 1973: Founded as Research Machines Limited in Oxford by Mike Fischer and Mike O’Regan.
  • 1974: Operated under the name Sintel, a mail-order supplier of electronic components for hobbyists. 

The Z80 Era (1977–1984)

  • 1977: Launched the RML 380Z, an 8-bit microcomputer based on the Zilog Z80 processor. It typically ran the CP/M operating system and was often housed in a distinctive large black metal case.
  • 1982: Introduced the RM Link 480Z.
    • Purpose: Designed as a diskless network node for schools.
    • Networking: Used the proprietary CHAIN Network or Z-Net to connect to a 380Z file server.
    • Hardware: Featured a Z80 CPU and up to 256 KB of bank-switched RAM. Early models had black metal cases, later replaced by cream plastic. 

The Nimbus & PC Transition (1985–1990s) 

  • 1985: Launched the RM Nimbus PC-186, using the Intel 80186 processor. While not fully IBM-compatible, it could run early versions of Microsoft Windows (up to 3.0).
  • 1986: Released the RM AX (using the Intel 80286), often used as a file server for Nimbus networks.
  • Late 1980s: Introduced the M Series (PC-286/386) and S Series (PC-386 and later), which were fully IBM PC compatible. 

The PC Era & Diversification (1994–Present)

  • 1994: Floated on the London Stock Exchange as RM plc.
  • 1997: Introduced the C Series of computers for schools.
  • 2003: Launched the F Series (blue chassis) pre-installed with Windows XP.
  • 2010: Released a new line of black and silver RM computers for Windows 7.
  • Current: RM has pivoted from hardware manufacturing to becoming a global EdTech solutions provider, focusing on digital assessment (RM Ava) and managed IT services.

Rational Unified Process RUP Overview and Timeline History

The Rational Unified Process (RUP) timeline is a two-dimensional framework where the horizontal axis represents time (divided into phases and iterations) and the vertical axis represents work/activities (divided into disciplines). 

Rational Unified Process, RUP

The process is structured into four sequential phases, each culminating in a major milestone where the project’s progress is assessed before moving forward. 

RUP Phases, Iterations and Workflows

RUP Project Phases and Milestones

Each phase of the RUP lifecycle has a specific objective and a corresponding milestone. 

  • Inception Phase
    • Goal: Define project scope, identify business risks, and establish the Business Case.
    • Milestone: Lifecycle Objective Milestone – Stakeholders agree on scope and cost/schedule estimates.
  • Elaboration Phase
    • Goal: Analyze requirements in detail and design a stable Software Architecture.
    • Milestone: Lifecycle Architecture Milestone – The architecture is validated and major risks are mitigated.
  • Construction Phase
    • Goal: Build the software system by developing and testing all components and features.
    • Milestone: Initial Operational Capability Milestone – A product is ready for beta testing by users.
  • Transition Phase
    • Goal: Deploy the software to the end users and perform final Beta Testing and training.
    • Milestone: Product Release Milestone – The development cycle is finished and the product is formally accepted. 

Detailed Iteration Timeline

Within each phase, work is performed in iterations (typically lasting 2 to 6 weeks). Each iteration is a mini-lifecycle that includes: 

  1. Requirements Analysis: Refining what needs to be built.
  2. Design: Modeling the system architecture and components.
  3. Implementation: Writing the code for specific features.
  4. Testing: Verifying the quality of the iteration’s output.
  5. Assessment: Evaluating the iteration against its planned goals. 

Historical Development Timeline

  • 1988: Objectory AB defines the core process.
  • 1995: Rational Software Corporation acquires Objectory.
  • 1998: RUP 5.0 is released, introducing UML integration.
  • 2003: IBM acquires Rational Software.
  • 2012: RUP is largely succeeded by Disciplined Agile Delivery (DAD) and SAFe.

BASIC programming language timeline history by year

BASIC (Beginner’s All-purpose Symbolic Instruction Code) was designed to make computing accessible to non-scientists, evolving from a simple teaching tool into the foundational language of the personal computer revolution. 

The Academic Era (1964–1974)

  • 1964: Invention at Dartmouth. John Kemeny and Thomas Kurtz created BASIC at Dartmouth College to allow students in non-technical fields to use computers.
  • 1964: First Execution. The first BASIC program ran on 1 May 1964, on a GE-225 mainframe.
  • Philosophy of Simplicity. It featured an intuitive, English-like syntax and was originally a “compile-and-run” language rather than a slow interpreter.
  • Time-Sharing. BASIC was designed for the Dartmouth Time-Sharing System (DTSS), allowing multiple users to program simultaneously from different terminals. 

The Home Computer Revolution (1975–1980s) 

  • 1975: Altair BASIC. Bill Gates and Paul Allen developed a BASIC interpreter for the MITS Altair 8800, which became Microsoft’s first product.
  • The “De Facto” Standard. By the late 1970s, BASIC was pre-installed in the ROM of almost every major home computer, including the Apple II, Commodore PET, and TRS-80.
  • Interpreted vs. Compiled. To save memory (often limited to 4KB), these versions were typically “interpreted,” meaning the computer translated code line-by-line during execution.
  • Hobbyist Culture. Magazines and books published “type-in” programs, allowing millions of users to learn coding by manually entering BASIC code. 

The Professionalization & Decline (Mid-1980s–1990)

  • Structured Evolution. Microsoft released QuickBASIC (1985), which introduced structured syntax (removing the need for line numbers) and a compiler for faster performance.
  • Rise of C and Pascal. Professional developers began shifting toward more powerful languages like C and Pascal as hardware became capable of supporting them.
  • Shift to Applications. As pre-written commercial software became common, the average user stopped writing their own programs in BASIC. 

The Visual & Enterprise Era (1991–Present)

  • 1991: Visual Basic (VB). Microsoft combined BASIC with a graphical user interface (GUI) designer, allowing developers to “drag and drop” buttons and forms.
  • Dominance in Business. By 1998, an estimated two-thirds of Windows business applications were built using Visual Basic 6.0.
  • 2002: Visual Basic .NET. Microsoft transitioned the language to the .NET framework, turning it into a fully object-oriented language.
  • Modern Status. While C# has surpassed it in popularity, VB.NET remains a stable, maintained language used heavily for maintaining legacy systems and Office automation.

  • July 1982: Timex Sinclair 1000 launched in the US as a licensed version of the ZX81, featuring 2KB of RAM (double the original’s 1KB).
  • 1982 Peripheral Boom: Numerous third-party upgrades were released, including the Memopak 64K RAM expansion and various replacement “real” keyboards to solve the frustration of the original membrane design. 

The Shift to Spectrum & Decline (1982–1986) 

  • 23 April 1982: Sinclair launched the ZX Spectrum, the colour-capable successor that would eventually overshadow the ZX81.
  • 1983: Total production of the ZX81 surpassed 1.5 million units worldwide.
  • 1984: The ZX81 was officially discontinued as Sinclair focused on the Spectrum and the ill-fated Sinclair QL.
  • 7 April 1986: Following financial difficulties, Sinclair Research’s computer assets were sold to Amstrad for £5 million.
