The early 1980s were a time when every manufacturer dreamed of creating the “computer of the future.” Around the world, companies tried to predict what users would want: better graphics, faster processors, unique programming languages – or simply a completely different design philosophy. Some visions were incredibly ambitious; others, just plain strange. But they all shared one goal: to break the mold and outpace the competition. Here’s the story of computers that wanted to change the world, but the world wasn’t quite ready for them. Enterprise 64/128 – Delayed Genius from the UK Launch: 1985 (originally announced in 1983) Enterprise was a computer that could have reshaped the industry—if only it had launched on time. Designed by Intelligent Software in the UK, it was meant to challenge the ZX Spectrum and Commodore 64. When announced in 1983, its specs sounded like science fiction: a 4 MHz Z80 CPU, up to 128 KB RAM, 672× resolution (interlaced), 256-color palette, and an advanced EXOS operating system. At its heart were two custom ASIC chips named “Nick” (graphics) and “Dave” (sound/memory paging), created by Nick Toop and Dave Woodfield. These were some of the most advanced integrated chips of their time. Anecdote:During development, the computer changed names multiple times – from “Samurai” (taken by Hitachi), to “Oscar,” then “Elan,” and finally “Enterprise.” Some joked it had more names than units sold. Specs: Due to a two-year delay, it launched in 1985 – too late. Cheaper alternatives like the Amstrad CPC 464 had already taken over. Despite its technical brilliance, only about 80,000 units were sold.

Unlike its plastic rivals, it featured a brushed anodized aluminum case, giving it the look of high-end hi-fi equipment. Available in MTX500 (32 KB), MTX512 (64 KB), and RS128 (128 KB), it came with a 4 MHz Z80A, TMS9929A graphics, and SN76489AN sound. It had a 79-key typewriter-style keyboard, separate numeric and function key blocks, and came with a built-in Z80 assembler and PANEL monitor for real-time register tracking. Trivia:Memotech planned to enter the Soviet market – with demo models using red keyboard overlays. The deal, however, never materialized. Specs: Despite its quality, MTX was too expensive compared to the £99 ZX Spectrum. About 250,000 units were sold, mostly in the UK and Europe.

It was the only home computer that booted directly into Forth. Forth used reverse Polish notation – e.g., “3 2 +” instead of “3 + 2.” While powerful and compact, it was tough for beginners. Though it had just 3 KB of user RAM, its efficiency allowed surprisingly complex programs. Anecdote:Its manual opened with: “In 1950, the National Physical Laboratory built the Pilot ACE… Now, in 1982, Jupiter Cantab has built its own ACE.” A clear nod to the original ACE computer. Specs: Only about 5,000 units were made. Today, they’re highly sought after by collectors.

All BASIC numbers were BCD floating-point – unique for its time. It came in 48 KB (£225), 96 KB (£299), and 128 KB (£345) models, with the 128 KB version running at 6 MHz (vs. 4 MHz standard). Unfortunately, only a few bytes of the graphics memory could be updated during horizontal sync – making graphics painfully slow. No hardware sprites or sound support further hampered game performance. Specs: Camputers went bankrupt in June 1984. Sales were poor compared to rivals.

It used the same Z80A CPU, TMS9918A graphics, and AY-3-8910 sound chip that MSX would adopt. Its main weaknesses were a chiclet keyboard, clumsy built-in joystick, and only 16 KB RAM, limiting performance. Trivia:Though not technically MSX-compatible (due to different I/O and memory layout), it was marketed in the UK as “the first MSX software-compatible computer.” A technically true, but misleading claim.

It featured a 3″ Hitachi floppy drive when most machines used cassettes, and became a favorite development platform for its stability and memory. Specs: Its price was too steep for home users. Only around 5,000 were made.

Its downfall? Huge defect rates – 60% of early units were returned. It was also oddly designed: powered through the printer, and booted into a word processor instead of BASIC. Anecdote:Coleco aimed to ship 500,000 units by Christmas 1983. They managed only 95,000, and the Adam was discontinued by January 1985.
