Olivetti RST-300: A Beautiful Lie

I recently stumbled upon a fascinating article about the Olivetti RST-300, which supposedly was a yellow personal computer directed by Mario Bellini and unveiled in 1983.

The "il canarino digitale" (digital canary) featured such captivating details as a distinctive startup melody, the Steve Jobs story, and Klein blue prototypes. However, after searching the internet, I discovered that this machine never existed. While Olivetti did manufacture word processors in the 1980s, the RST-300 was never among them.

So it remains a wonderful fictional concept that never came to life.

Apple I (1976)

Steve Wozniak had wanted to build his own computer for a long time. He finally started when he found the MOS Technology 6502 chip, which cost only 25 dollars instead of the 175 dollars Motorola asked for the 6800. He wrote the BASIC interpreter first, and then designed the computer around it, with a keyboard instead of switches and a video output you could connect to a TV.

A small 256-byte "monitor" program started when you turned the machine on. With it you could enter hex bytes, look at the memory, and run programs. The whole computer fit on one board, about 16 by 12 inches, with only 30 to 40 chips and up to 8 KB of RAM. It had no speaker, no graphics, and no color.

Steve Jobs suggested that they make printed circuit boards, and on April 1, 1976 they founded the Apple Computer Company. Paul Terrell, the owner of the Byte Shop, ordered 50 units, but he wanted them fully assembled.

So the two Steves built the machines in Jobs' garage, though they still came without a power supply, keyboard, or monitor. The Apple-1 came out in July 1976 for 666.66 dollars. They made 200 units and sold 175 of them within ten months.

At Terrell's request, Wozniak also designed a 75-dollar cassette interface card. It ran at 1200 baud, which was four times faster than most machines of that time.

Production ended in March 1977, when the Apple II arrived.

The Grid Compass: The First Laptop in Space

The Grid Compass debuted in 1982 and revolutionized the world of portable computers. On November 28, 1983, the first unit launched aboard NASA's Space Shuttle Columbia, making it the first laptop to reach space. British industrial designer Bill Moggridge created the iconic clamshell design, which became the foundation for all modern laptops. NASA used the device as SPOC (Shuttle Portable On-Board Computer) for onboard navigation and telemetry purposes.

Technical Specifications:

Processor: Intel 8086 16-bit

RAM: 256 KB

Non-volatile memory: 384 KB bubble memory

Display: 9.5-inch electroluminescent, 25x80 characters

Modem: 300/1200 baud

Case: magnesium alloy

Weight: approximately 11 pounds (5 kg)

Price: USD 8,150 (1982)

The Grid Compass was incredibly rugged. It even survived the 1986 Challenger disaster and continued to work. Today, it is preserved in the Smithsonian Museum as one of the most important computer innovations in space exploration history.

Atari Falcon (1992)

The Atari Falcon030 was unveiled in 1992 and was the last personal computer designed in-house by Atari Corporation. Its name comes from the built-in Motorola 68030 processor.

Hardware

CPU: Motorola 68030, 16 MHz (which was relatively slow even at the time)

DSP: Motorola 56001 DSP chip – one of its most important innovations, running at 32 MHz

RAM: 1 or 4 MB on the motherboard, expandable up to 14 MB

Graphics: up to 65,536 colors (16-bit True Color) at 320×200 resolution, or 256 colors at higher resolutions

Sound: 16-bit stereo audio system with outstanding audio quality thanks to the DSP

Operating System: Atari TOS 4.x (compatible with earlier ST machines)

Why Was It Special?

The DSP chip was its real strength: capable of real-time audio processing, MIDI, sound synthesis, and even audio compression – which was quite rare at the time

It was designed as a multimedia machine and found some success among studios and musicians

It was cheaper than a Mac or PC, yet offered comparable (or better) multimedia capabilities

Problems and Downfall

The 16 MHz CPU speed felt outdated at a time when the Amiga 1200 and PCs were running significantly faster

Atari was struggling with financial difficulties, and marketing and distribution were weak

Few software titles were developed for it, and developers largely ignored it

In 1993, Atari withdrew from the computer market and focused on gaming consoles (the Jaguar)

Sinclair Cambridge Programmable Pocket Calculator

The Sinclair Cambridge series was introduced by Sinclair Radionics in the summer of 1973, eventually growing from a basic four-function model into a range of seven variants. The Programmable version appeared in 1975 and was one of the earliest affordable programmable pocket calculators on the market.

Technical specifications: The display was an 8-digit red LED unit manufactured by National Semiconductor. Inside, the calculator used National Semiconductor MM5799EHY/N and DS7784N integrated circuits. It featured a single memory register, a maximum of 36 program steps, and a conditional jump instruction. Its dimensions were a compact 50 × 111 × 28 mm.

Power supply and design: While the original Cambridge ran on four AAA batteries, the Programmable required a 9V PP3 battery, which created a distinctive bulge on the back of the case — playfully referred to as the "pregnant" design by enthusiasts.

Accuracy and limitations: The scientific functions had limited precision, yielding only four significant digits in some cases. This was a weak point compared to competitors, but the low price more than made up for it.

Program libraries: The calculator came with a four-volume program library covering general/finance/statistics, mathematics, physics/engineering, and electronics.

Sales and distribution: In the United States it was sold under the name Radio Shack EC-4001, as Sinclair supplied the Radio Shack electronics chain. The Cambridge Programmable was eventually succeeded by the Sinclair Enterprise, which offered an expanded capacity of 80 program steps.

Commodore MAX (1982)

Retro Computing's Most Forgettable Little Weirdo

1982, Tokyo. A machine appears, originally codenamed the Commodore VICKIE. And then almost everyone forgot it existed.

The Commodore MAX Machine (also known as the Ultimax in the US, and the VC-10 in Germany) is one of the most fascinating footnotes in retro computing history. It launched in Japan in November 1982, and was a close cousin of the legendary Commodore 64, sharing a huge number of components with it. So what went wrong?

The Tech

The specs don't actually sound that bad at first glance:

CPU: MOS Technology 6510 @ 1.02 MHz

RAM: 2 KB + 0.5 KB color RAM

Graphics: VIC-II 6566 (320x200, 16 colors, sprites)

Sound: 6581 SID chip (yes, the exact same one as in the C64)

And the design? A silver-and-black chassis with red accents. Before the C64's iconic beige-grey became the industry standard, this machine looked like a prop from a sci-fi film...

The Problem

Only 2 KB of RAM. For reference: the Commodore PET from five years earlier shipped with a minimum of 4 KB. The MAX was clearly designed as a game console, not a real computer.

There was no built-in operating system, no serial port, and no way to connect a disk drive, printer, or modem. A tape drive was technically possible, but since every tape-handling routine had to be implemented by the cartridge itself, only 2 of the 24 released titles actually supported tape storage.

And then there was the competition: Commodore's own VIC-20 cost roughly the same price but came with far more software, expandability, and a proper keyboard.

The Legacy

Only around 50,000 units were ever produced in 1982. Then it was quietly discontinued.

But the MAX didn't die entirely. Its cartridges worked on the C64 as well, and it directly paved the way for legendary "freezer" cartridges like the Action Replay, because Commodore baked "Ultimax mode" into the C64 specifically to maintain MAX compatibility.

JUPITER ACE (1982)

the home computer that refused to speak BASIC

Every single home computer in 1982 ran BASIC. Every single one except this little white box from Cambridge.

the origin story

Two engineers walk out of Sinclair Research and decide to build their own machine. Steve Vickers wrote the ZX Spectrum's BASIC. Richard Altwasser designed its motherboard. Their verdict on BASIC? They weren't fans.

"Comparing Forth to Basic is like comparing a Gothic cathedral to a mud hut." — Steve Vickers, 1982

They named their company Jupiter Cantab, rented a spare room in Altwasser's house in Cambridge, and got to work.

what made it weird

The Ace ran FORTH — a language where you stack tiny building blocks called "words" on top of each other. Alien syntax, steep learning curve, and absolutely beautiful to the right kind of mind. It ran 10× faster than BASIC on identical hardware. The machine had a Z80A chip, 3KB of RAM, and cost £89.95.

No colour graphics. No software library to speak of. Just raw, elegant speed.

the rise and fall

April 1982 ZX-Spectrum launches. Vickers & Altwasser quietly start planning their exit.

September 1982 Jupiter Ace goes on sale. Built in a spare room.

December 1982 Stocked by Laskys and Debenhams. Christmas boom. Optimism.

July 1983 Altwasser quits to be with his newborn. The writing is on the wall.

November 1983 Jupiter Cantab folds. 14 months of existence. £140K in debt.

why it failed (and why that's sad)

The market wanted games. Kids wanted BASIC. The Ace had monochrome graphics, almost no third-party software, and a language that required you to think differently. It wasn't a bad machine — it was a machine built for a world that didn't exist yet.

"We sold a lot of machines to the few hundred Forth enthusiasts — and that was it." — Steve Vickers, looking back

Around 5,000 units were ever made. Today they're collector's items. The people who own one treat it like a relic — and honestly, they're right to.

Amstrad CPC464 (1984)

The Amstrad CPC464 arrived in 1984, two years after the launch of the ZX Spectrum, and quickly became one of the standout home computers of the decade in Europe.

Its success came from the fact that it offered not just a computer, but a complete and user friendly system.

With its built in cassette deck and, in many cases, its own dedicated monitor, it looked more modern and more neatly packaged than many of its rivals.

Its development was not entirely smooth, as the early plans changed several times before the final design was completed.

Once it reached the market, however, the CPC464 quickly proved that Amstrad understood exactly what home users of the era wanted.

It was stylish, practical, and had a surprisingly serious presence in the living room.

Under the case was a Z80A processor running at 4 MHz, paired with 64 KB of memory.

Sound came from a three channel AY chip, which helped create the distinctive audio world of the era’s games and demos.

The CPC464 also offered multiple graphics modes, allowing developers to balance detail and color depending on the needs of the software.

One of its real strengths was the built in Locomotive BASIC, which was widely praised for its speed and ease of use.

It is no surprise that the CPC464 remains a true retro legend, a machine that still brings back memories of games, cassette loading, and the unmistakable magic of 1980s home computing.

SONY Hit-Bit HB-101 (1984)

The Sony Hit-Bit HB-101 is one of the best-known and most distinctive Sony MSX1 home computers from the 1980s. “Hit-Bit” was Sony’s MSX product line name, and the HB-101 is still popular among retro collectors because of its compact, highly recognizable design.

Technically, it’s a classic MSX1 machine: a Sharp LH-0080 (Z80A-compatible) CPU at ~3.58 MHz, 16 KB RAM (the European HB-101P version often had 32 KB), 16 KB VRAM, and 2 cartridge slots, which made it very practical for games and expansions.

The video chip can vary by region (TMS9118NL / TMS9129NL), while sound is handled by the YM2149F PSG. It wasn’t the most powerful MSX model, but its Sony styling, colorful variants, and iconic look are exactly why it became such a cult favorite.

Commodore 64G, the White C=64

The C=64G is more than just a “white C64” — it’s one of the last commercially sold versions of the Commodore 64, and a very interesting late-era hybrid. It kept the classic breadbox-style case, but in a much lighter color similar to the C64C, reflecting late-1980s design trends.

What makes it especially interesting from a hardware perspective is that many C64G units used a smaller, simplified motherboard design (similar to late C64 variants), although some machines reportedly still shipped with older-style C64 boards. This mix-and-match nature also showed up in keyboards and internal parts, suggesting Commodore was using whatever stock was available at the end of the C64 production era.

The C64G is also commonly associated with the MOS 8580 SID chip, which changes the behavior of sampled sound compared to older 6581-based machines (notably much lower playback volume unless modified).

So from a collector and hardware enthusiast point of view, the C=64G is a great example of Commodore’s late production strategy: a classic exterior, newer internal revisions, and a lot of variation between individual units.

Commodore Amiga 3000UX

The Amiga 3000UX is a variant of the Amiga 3000 that Commodore positioned specifically for UNIX-oriented use. The “UX” designation does not refer to user experience; it indicates that the machine was offered together with Commodore Amiga UNIX, known as AMIX. AMIX was an Amiga port of AT&T UNIX System V Release 4 (SVR4), intended to bring the A3000 closer to the workstation-style requirements of its era.

In hardware terms, the 3000UX is largely based on the standard Amiga 3000 platform, so it is not a completely separate class of machine. The differences were mainly in the package, the bundled software, and especially the AMIX-related Kickstart 1.4 ROM. The goal was to make the system usable not only in the AmigaOS/Workbench environment, but also for UNIX-based workflows, including graphical setups such as an X Window environment.

Because it remains fundamentally an Amiga 3000, the 3000UX is often regarded as one of the more “professional” Amiga models. At the time, its built-in SCSI and expandability—particularly through the Zorro III bus—made it attractive for work, development, desktop publishing, and graphics and video production.

Family portrait of the relatives who never forget what uptime means...

PDP-11/70 // the heavyweight. front panel like a tiny city at night. blinkenlights that feel weirdly calming, like watching rain on a window.

PDP-11/44 // the reliable one. the “yeah, i’ll just do the job” energy. quietly competent.

VAX 4000-705A // the slightly newer sibling who still carries that machine-room aura in its bones.

Not retro decor. not props... actual history that still boots, still clicks, still hums, still gets warm in the way modern computers refuse to. There’s something comforting about hardware that has presence.

Macintosh IIcx (1989)

There’s something quietly iconic about the IIcx: a workstation-era Mac that looks restrained, tidy, and confident. Same 68030-era muscle as its bigger sibling, but in a slimmer case that feels more “designed” than “industrial.”

Motorola 68030 @ 16 MHz — fast, serious, and very late-80s pro

3× NuBus slots — enough room for real expansion without the huge tower vibe

Memory monster potential — 30-pin SIMMs, built to scale up

Apple Macintosh XL (1985)

Here’s a weird, underrated footnote in Apple history: the Macintosh XL was essentially an Apple Lisa 2 rebranded as a Macintosh. Apple’s goal was simple—move remaining Lisa inventory and reposition it for the growing Mac ecosystem.

What made it “Mac”? The key was MacWorks XL, software that enabled Macintosh (64K ROM) emulation, letting the machine run many Mac apps—while still retaining its Lisa roots.

Launched January 1, 1985

Motorola 68000 @ 5 MHz

Sinclair ZX-81

The Sinclair machines were among the cheapest (especially in the USA), the second machine, the ZX-81, was a great leap forward from the ZX-80.

Therefore, the price also increased, but it could be purchased optionally in a set at a price of $99.95. In 1981-82, this price was quite 'ridiculously low' - just for comparison: Atari 400 16Kb was $329, Atari 800 was $699, but even the Texas Instruments TI-99/4A, which had been devalued due to the market crash, was $379.

ZX-81 was not successful in the USA, but it managed to sell 1.5 million units in the UK and EU (mainly due to its price).
