Why are DIY PCs a Thing? IBM Botched Office PCs in 1981

The Ford Model T of office PCs, the 1981-released IBM PC-100 (shown above) is a productivity tool as groundbreaking as Henry Ford’s  magneto assembly line.  Legendary indeed, but the 100 almost tanked IBM.

Back then, PC-100 gave office professionals plenty of compute power for file management, document production, database work. Its $1,500 price tag might classify it as the first workstation computer as we known them today. PC-100 was never intended to compete against Jobs and Wozniak for home use: after all, IBM stands for International BUSINESS MACHINES.

PC-100 targeted enterprises and medium-size businesses with the look of the emergent home PCs of the time. With its sibling computers, the IBM AX and dual-monitor supporting IBM AT, IBM PCs owned the B2B market.

Open-sourcing motherboard inputs, running a BIOS-based OS, and building with a modular design

Unprecedented for IBM, the company published motherboard schematics for PC-100 so third party vendors could design add-ons. Until then, IBM made its own custom components. For a more competitive price, IBM sourced the x86 CPU from Intel and turned to Japan for peripherals. It came with a Toshiba monitor and an Epson printer.

The innovative BIOS-mounted firmware designed to support Bill Gates’ MS-DOS, which IBM sold pre-installed at a lower price than if purchased separately. The same way that Newegg PCs come with Windows 10 today.

IBM decision-makers worked from the assumption that giving OEMs bus and BIOS specs weren’t enough reverse engineer replica machines. That was an epic miscalculation, as IBM would soon learn. IP suits went into the courts, and judges maintained reverse engineering from open source architecture is not an IP violation.

The Compaq Mobile (1982) cloned IBM PC hardware for what we might call the first PC laptop.

Back then, computers of the type were called ‘luggables’ because they folded up like a suitcase when traveling.

A harder blow to IBM came when Compaq delivered first with a PC using the latest 8086 Intel CPU.

Intel 386 VitualMode technology made multi-tasking with different applications possible. Microsoft took advantage by writing Windows 1.0 for 386 PCs.

IBM almost did not survive

The early 80s began a decade-long skid from IBM. It descended from near-Monopoly to almost-bankrupt; in 1993 IBM reported $5 billion in annual losses in FY 1992.

By the 1980s, IBM internal view of being the epitome of excellence in technology, customer service and respect for individual had strayed far from the reality. In spite of their heavy R&D spending, they had little to show for it, especially in breakthrough innovations. As exhibited by rivals CDC in Supercomputers and Compaq in PCs, when IBM could not control the market, it found it difficult to compete on the 3 Ps – price, performance and product features. IBM’s shift in from rentals to sales had triggered a decline in customer relations and those relationships were never salvaged.  — (Archie Russel, et al. Failures of Large Computer Companies,  University of Washington, Dec. 2006)

IBM powered through by maintaining leadership for mainframe and super computers for large enterprise and federal government. Shown below is the IBM 360.

Commodized PCs? Boring. Let’s build our own

As OEMs scrambled to release their own desktops PCs the industry grew more commoditized. The drawback of the race to the lowest price meant fewer custom-build options and more off-the-shelf configurations. Tech savvy enthusiasts took a DIY route and purchased specific components themselves. Intel ATX motherboards, big and roomy cases, high-wattage power supplies, performance graphics cards, and more.

The same paradigm applies today. Unless it’s a high power gaming PC or scientific workstation, building a PC for work is an unlikely route for a business to take. IT pros still do it out of principle, but for mainstream desktops the cost savings is often canceled by an OEM Windows license bundled in with HP, Dell, ABS, Toshiba, and other office PCs found on Newegg.
