PC Pro, Issue 309

PC Pro Issue 309This month’s PC Pro includes my hands-on review of the TBBlue ZX Spectrum Next, a crowdfunded reimagining of what home computers could have become if the market hadn’t crashed in the mid-80s.

Powered by a field-programmable gate array (FPGA), giving it the ability to transform into anything from a BBC Micro to a Galaxians arcade cabinet, the ZX Spectrum Next is around two years past its original launch schedule. The delay has been attributed to getting everything right, in particular the Rick Dickinson-designed chassis and keyboard – and, in TBBlue’s defence, the entire package is undeniably impressive.

For PC Pro’s testing I went hands-on with a production model of the top-end variant, the ZX Spectrum Next Accelerated. This features 1MB of memory upgradeable to 2MB, which is a lot if you’re thinking in 1980s terms, with a pre-fitted real-time clock and Wi-Fi module to match the mid-range Plus model. The stand-out feature of the Accelerated version, though, is a Raspberry Pi Zero fitted internally to act as a coprocessor – a concept gently borrowed from the BBC Micro and its Tube socket, to which the world’s first Arm processors were connected.

It wasn’t my first experience with the ZX Spectrum Next: I reviewed an early revision of the motherboard, minus case and keyboard, two years ago. In that time, though, the company and the community behind the project have worked to really polish things up: there’s a wire-bound printed manual, though sadly lacking an index; the operating system is swish and the bundled games impressive; the lost 28MHz ultra-fast accelerated operation mode is back, after being dropped in favour of a 14MHz mode following timing issues with the RAM; and while some features aren’t quite ready, in particular the ability to load multiple FPGA cores into a menu and choose from them at boot-up, it’s already a device that will appeal to vintage computing enthusiasts.

The full review is available now in PC Pro Issue 309, available at your nearest stockists or online in print or digital formats.

PC Pro, Issue 302

PC Pro Issue 302Following on from my group test of small form factor machines in Issue 297, this month’s PC Pro magazine sees me take the helm of the regular Labs Test once again to put nine more traditional desktop PCs through their paces – with some available for as little as £300 including a Windows 10 Home licence.

The feature follows the usual Labs format: an introduction is followed by a features table listing all the key specifications, including pricing and warranty data, on each of the nine machines on-test; four large focus reviews follow, along with six shorter reviews; there’s a two-page buyer’s guide with hints and tips on getting the most bang for your buck; the View from the Labs opinion editorial; and a full-page feature-in-feature which, this month, takes a tour of the desktop PC’s storied history from the minicomputer era forwards – with special mention, of course, to IBM’s Personal Computer and the horde of ‘IBM Compatibles’ which followed.

Each machine on test was photographed inside and out in my in-house studio, disassembled to check the fit and finish as well as confirm how upgradeable each design is post-purchase, and tested through a gamut of benchmarks including power draw, productivity performance, gaming performance – less of a focus for this Labs than most, owing to the fact many machines are at the very bottom of the budget and designed more for general-purpose computing than blasting aliens – as well as browser performance and disk speed. This Labs also comes with an added bonus: boot timings for each machine, measuring how long it takes each to load Windows ready for use from a cold start.

As always, these group tests wouldn’t be possible without the cooperation of the hardware vendors themselves. My thanks go out to CCL, Palicomp, PC Specialist, QuietPC, Chillblast, Cyberpower, and Currys PC World for their assistance with hardware loans, and also to Box.co.uk for the loan of a system which was unfortunately not able to be included in the group this time around. A special thanks, too, goes to UL Benchmarks and Unigine for the provision of benchmarking software used in the test.

The full feature is available in PC Pro Issue 302, on-shelves now at supermarkets, newsagents, and on the hard drives of the usual digital distribution services.

PC Pro Issue 298The big news of the last few weeks has, of course, been the launch of the Raspberry Pi 4 single-board computer – covered in considerable detail in my benchmark piece over on Medium. To support its in-house review coverage, PC Pro Magazine commissioned me to come up with project ideas that take full advantage of the Raspberry Pi 4’s new capabilities.

The first of a new family of Raspberry Pi products designed to do away with some of the biggest criticisms levelled at earlier models, the Raspberry Pi 4 includes a significantly more powerful processor, improved graphics capabilities, dual-4K video output and hardware H.265 4K video decoding, up to 4GB of RAM, true gigabit Ethernet networking, and two USB 3.0 ports sharing a high-speed PCI Express link back to the Broadcom BCM2711B0 system-on-chip (SoC) at the board’s heart.

My feature covers how these new capabilities can be used in a variety of real-world use-cases, from acting as a desktop replacement for lightweight browsing and productivity use to a low-power 4K-capable home cinema system. The new USB 3.0 ports are perfectly suited to turning a couple of external hard drives into a low-cost network-attached storage (NAS) system, while the improved graphics make gaming more tempting.

There’s even something for the enterprise crowd to sink its teeth into: the dual display capabilities mean that the Raspberry Pi 4 is perfect for digital signage, Citrix support on day one turns it into a dual-screen thin client, and the more powerful networking can be combined with a USB 3.0 Ethernet adapter to create an energy-efficient router, firewall, or other network appliance.

For the full low-down on what the Raspberry Pi 4’s new features could do for you, pick up the latest PC Pro from your nearest supermarket, newsagent, or digitally via Pocketmags or similar services.

PC Pro Issue 297The Labs Test in this month’s PC Pro is something of a bumper one: I ran a whopping 14 miniature PCs, from a cleverly cased Raspberry Pi up to a behemoth of a system squeezing in an Nvidia GeForce RTX 2080, through a gamut of tests including size and weight, power draw, productivity and gaming benchmarks to see which would come out on top.

The work of a solid few weeks, the Labs saw system after system bouncing onto and off the test bench. As well as requiring the actual testing, all photography was carried out in-house – with thanks to my wife, who served as a hand model for the article’s hero shot – with each system photographed from all angles and internally, plus a smart isometric view in which the scale is maintained so the reader can easily compare the relative sizes of each machine on test. Given that the feature is about miniature PCs, such easy at-a-glance comparison is key to knowing which machine meets the readers’ personal requirements.

A Labs Test like this wouldn’t be possible without the cooperation of a range of companies, of course, and I’d like to thank the suppliers of machines for the test: ASRock, Asus, Intel, Mini-ITX.com, Lenovo, QuietPC, Raspberry Pi, and Shuttle. Additional thanks go to Intel, Nvidia, and Overclockers UK, who provided components required to build up the bare-bones systems on test.

As is traditional for a PC Pro Labs Test, the content is split between reviews – four 700-word focus reviews and ten 350-word supplementary reviews – and features, including an interview with Intel’s Ed Barkhuysen on the company’s modular vision for the future of computing, a buyer’s guide covering things to consider when making the move to an ultra-small-form-factor (USFF) system, a two-page features table covering everything you could want to know about each system on test, a look at external GPU (eGPU) products as a way of expanding the performance of mini-PCs, and a “View from the Labs” opinion editorial to round things out.

This feature also marks the first time the in-house PC Pro benchmark suite – which measures system performance for image editing, video playback, and multitasking workloads – has been run not only on Linux-based, rather than Windows, systems but also on a Raspberry Pi. To achieve that, I worked to port the PowerShell-based suite to the Bash shell while using the same cross-platform applications to ensure each platform can be compared as fairly as possible.

PC Pro Issue 297 is available now at all good supermarkets, newsagents, and digitally via Zinio and similar services.

PC Pro, Issue 279

PC Pro Issue 279This month’s PC Pro includes a review of something a little out of the ordinary: the open-source, microcontroller-powered OpenScope MZ oscilloscope from Digilent.

Based on the original OpenScope and manufactured following a highly successful crowdfunding campaign, the OpenScope MZ is designed primarily for education and hobbyist use. While it lacks the bandwidth you’d need for professional use, it makes up for it in ease of use: it can be connected to your wireless network for tangle-free operation, includes cables which mate handily with the 2.54mm headers common to hobbyist electronics, and uses cross-platform software capable of running on everything from a powerful desktop to a low-end smartphone.

Better still, the OpenScope MZ is, as the name implies, open: the hardware design, firmware, and software are open source, allowing anyone with the knowledge to add features or customise the device as they see fit.

More information on the OpenScope MZ is available on the official website, while you can read my review in full by picking up a copy of PC Pro Issue 279 from your nearest newsagent, supermarket, or digitally via Zinio and similar services.

PC Pro Issue 277This month’s issue of PC Pro includes a four-way Battle Royale of DIY handheld games consoles, starting with the MAKERbuino and Creoqode 2048 also reviewed in this month’s Custom PC and including the original Gamebuino and Arduboy to complete the round-up.

There’s never been a higher focus on teaching kids to program – not even during the height of the microcomputing boom in the 1980s, when every home had a Spectrum and every school a BBC Model B partially funded by the government’s Computers in Schools initiative – but there’s a risk of turning kids off if all they’re doing is moving sprites around on a screen. To address this, a number of inventors have come up with physical devices to target instead: from the BBC micro:bit, the spiritual successor to the original Acorn-designed BBC Micro, to the handheld consoles in this month’s group test.

Each of the consoles on test have two things in common. The first is obvious: the focus is more on writing your own games, rather than just playing things other people have created. The second lies under the hood: all four consoles on test are based on Atmel microcontrollers and are compatible with the popular Arduino IDE programming environment.

There are more differences than similarities, though. The Creoqode 2048 is the most physically impressive – and imposing – machine on test thanks to its large footprint and bright RGB LED display, but falls down with poor supporting documentation and rebranded off-the-shelf parts sold at a massive markup; the Arduboy is, by contrast, the tiniest on test with a wallet-friendly design but limited capabilities. The Gamebuino has long been one of my favourite Arduino-compatible projects, but the MAKERbuino takes the concept a stage further with small hardware improvements and a shift from a pre-assembled unit to a solder-it-yourself kit using entirely through-hole components.

If you want to know which device walks away as the king of the hill, though, you’ll have to pick up the latest issue of PC Pro either physically at all good newsagents and supermarkets or electronically via Zinio and similar distribution services.

PC Pro, Issue 271

PC Pro Issue 271In this month’s PC Pro Magazine I take a look at possibly the least original product to have ever come out of Asus’ labs: the Raspberry Pi clone known as the Tinker Board.

Designed to help Asus capture a slice of the lucrative maker market, the Tinker Board is a one-for-one feature-and-footprint clone of the Raspberry Pi 3: it’s a roughly credit-card-sized single-board computer with an ARM processor, wired Ethernet, Wi-Fi and Bluetooth radios, four USB 2.0 ports, an HDMI port, analogue audio, Camera Serial Interface (CSI) and Display Serial Interface (DSI) ports, and a 40-pin general-purpose input-output (GPIO) header. So far, so cloned.

Where Asus has tried to improve upon its inspiration is in the raw specifications: the processor, while 32-bit to the Raspberry Pi 3’s 64-bit, is considerably faster; there’s double the memory, a supposedly gigabit network connection which isn’t bottlenecked by a single-channel USB bus, support for 4K video playback, and high-resolution 24-bit 192KHz audio. If all of that were true, it’d be easy to overlook the higher selling price of the Tinker Board compared to the Pi on which it is based.

Sadly, my review didn’t go smoothly. The Tinker Board has hit the market in a parlous state. The 4K video playback is choppy, the GPIO port barely works and none of its features beyond simply toggling a pin on and off are available, hardware accelerated video playback is barely functional, and the ‘gigabit’ Ethernet port no faster than the 10/100Mb port on any standard Raspberry Pi.

To be fair to Asus, the majority of the problems I encountered – bar, possibly, the Ethernet performance – were likely related to the software provided, which appears to be in a very early alpha stage. It’s a device I’ll be keeping to one side in the hope of revisiting it in the future, should Asus ship improved software.

For a full run-down of my experience with the board, pick up the latest PC Pro at your nearest supermarket, newsagent, or electronically on Zinio and other digital distribution platforms.

PC Pro Issue 269In this month’s PC Pro I turn my eye to the Kano Computer Kit, the latest bundle of parts from the eponymous London-based education-centric company – and come away with distinctly mixed feelings.

The original Kano kit proved a smash hit when it landed on crowdfunding site Kickstarter back in 2013, raising more than $1.5 million to produce what it claimed was a computer you built yourself. Its launch was marred, however, by a modicum of controversy: what Kano had made was not a computer, but rather a selection of accessories – case, speaker, keyboard, and a customised GNU/Linux operating system – which it bundled with the already-existing Raspberry Pi, turning it from the “computer you build” to the “computer you put in a case and plug a USB dongle into.”

The crowdfunding success was followed by efforts to set up a sustainable business, and the Kano kits are now available globally direct from Kano and through resellers. For review I received the two latest revisions, the Kano Computer Kit and Kano Display Kit, bundled together as the Kano Complete Computer Kit.

The Computer Kit takes a Raspberry Pi 3 then bundles it with the Debian-based Kano OS software, a case, GPIO-powered speaker, combined wireless keyboard and trackpad in fetching orange, and the Kano ‘story book’ manual. The Display Kit adds a non-touch display panel, a custom stand the Kano case can hook into, and a smart split power cable that allows the display and Raspberry Pi to be driven from a single socket.

The hardware, sadly, proved disappointing for the cost. At an RRP of £299, the kit isn’t exactly value for money: a Raspberry Pi 3, speaker, wireless keyboard and trackpad, official touchscreen display, power supply, micro-SD card, and a decent book could be had for around half the cost and provide roughly equal educational value – if, that is, you ignore the software.

Kano OS is, to put it simply, fantastic. For full details you’ll have to read my review, but it’s fair to say I was in love with the platform from the moment I powered the Kano kit on. Interestingly, though, you don’t need a Kano kit to use Kano OS: the Debian-based Linux distribution is available to download completely free of charge from Kano’s developer site, and can be used on any existing Raspberry Pi.

For my final conclusion, pick up the latest issue of PC Pro from your favourite supermarket, newsagent, or electronically via Zinio and similar digital distribution platforms.

PC Pro, Issue 268

PC Pro Issue 268My review for this month’s PC Pro is on a topic dear to my heart: hardware which not only fully supports the open GNU/Linux operating system, but even comes with it pre-installed. Specifically, it’s the Aurora laptop from Newcastle-based Nimbusoft.

Based on a Topstar Ultrabook chassis, the Aurora is designed to appeal to those who like Apple’s MacBook Pro and MacBook Air range. Though not as powerful as the former or slim as the latter, it’s a comfortable little laptop with a slick aluminium chassis – albeit one I would discover during dismantling is rather thinner than you might expect.

The hardware isn’t the main feature of the Aurora, anyway. Nimbusoft’s claim to fame is in being one of the few companies offering a range of hardware with a Linux distribution pre-installed. the company even goes further than its competitors in offering a choice of desktop environments, and I’m pleased to say that the review unit – specced with Ubuntu 16.04.1 running the stock Unity DE – proved to be entirely without bloat or branding, in stark contrast to Windows laptops I’ve looked at in the past.

Reviewing the laptop for PC Pro involved running it through a standardised battery life test: the looping of a film with the Wi-Fi and Bluetooth radios disabled and the display set to a brightness of 170cd/m². This makes my result of five hours exactly – give or take a couple of seconds – directly comparable with the magazine’s other reviews, even of tablet-style machines. Getting the display to exactly the right brightness, though, is always a challenge.

While the battery life proved slightly disappointing and the chassis rather thin, I came away from the Aurora rather pleased – but to get my final verdict on the machine you’ll have to pick up a copy of PC Pro Issue 268 from your nearest emporium of glossy print or digitally via Zinio or one of the many competing digital distribution platforms.

PC Pro Issue 267This month’s PC Pro magazine features an in-depth review of the NextThingCo CHIP and its PocketCHIP companion, crowd-funded open-hardware alternatives to the overwhelmingly popular Raspberry Pi.

NextThingCo’s crowdfunding launch was met with considerable scepticism, and with good reason: at a time when the Raspberry Pi had only just proven you could sustainable sell a fully-functional single-board microcomputer with desktop-ish performance for under $30, NextThingCo was claiming to offer the same thing for $9 – and with integrated Bluetooth and Wi-Fi radio connectivity to boot.

The campaign succeeded, and to critics’ considerable surprise nobody was ripped off: NextThingCo’s CHIP did indeed ship and, as of earlier this year, is now available to purchase direct. While certain corners have been undoubtedly cut – just like the Raspberry Pi, it comes devoid of cables and accessories – and its performance can’t hold a candle to newer Pi models, it’s functional, available, and if you’re willing to supply the extras needed to get it up and running yourself does indeed cost $9.

The PocketCHIP, meawhile, is a fantastic example of what you can do with a CHIP: an open-hardware hand-held computer, complete with clever though painful-to-use bubble-based keyboard, with a very 1990s transparent casing. The screen may be low resolution and resistive rather than capacitive touch, but if I said I didn’t have a blast using the PocketCHIP I’d be lying.

For my full verdict on the device, of course, you’ll have to head to your nearest PC Pro stockist, whether that’s a newsagent, a supermarket, or one of the digital distributors like Zinio you can browse from the comfort of wherever you’re reading this.
