Linux User & Developer, Issue 153

Linux User & Developer Issue 153In addition to my regular four-page news spread at the front of the magazine, this month’s issue of Linux User & Developer includes a review of the Gizmo 2 single-board computer – a powerful follow-up to the original, which I reviewed back in Issue 125.

Like its predecessor, the Gizmo 2 is based around an AMD Accelerated Processing Unit – specifically, the G-Series GX210HA dual-core chip running at 1GHz – in an open-hardware 4″-square board. Offering improved performance over the original model, the new Gizmo 2 is also available for the first time as a stand-alone system – although this does mean the death of the Explorer Kit, a bundle which included a handy-dandy break-out board for the PCIe-style low-speed expansion connector at the front of the board.

During my review, which took place a few months ago, I did encounter one issue: the BIOS refused to boot from the USB 3.0 ports, limiting OS installation to the Micro-SD Card slot or USB 2.0 ports. As the device offers so much performance – around 85 gigaFLOPS including the integrated Radeon HD 8210E graphics chip – that was a disappointing limitation, but one an updated BIOS has since resolved.

I was a big fan of the original Gizmo, which was significantly better than Intel’s rival MinnowBoard. Although the MinnowBoard Max has since levelled the playing field, I have to say that the Gizmo 2 would still be my board of choice for SBC tasks requiring high graphics performance or x86 compatibility – despite the addition of an annoying active cooling fan – but for my thoughts beyond that you’ll have to pick up a copy of the magazine.

If you do, you’ll find the review, my news spread, and a bunch of stuff written by other people. Linux User & Developer Issue 153 is available from all good newsagents and supermarkets now, or digitally via Zinio and similar services. My work will also appear in the translated Inside Linux magazine in France in the coming months.

Custom PC, Issue 140

Custom PC, Issue 140In this month’s Hobby Tech column I interview my friend and talented maker Bob Stone, review the ZoomFloppy accessory, and review the Gizmo 2 single-board computer, in roughly that order.

Looking at the interview first, I arranged to quiz Bob after bumping into him at an event a while back. Bob was present as a representative of York Hackspace, showing off a project they had been working on dubbed Spacehack. Inspired by a mobile game, Spacehack gives players the job of keeping a rusty old spaceship in one piece by performing various tasks on a physical control panel which remaps everything between rounds. If that weren’t confusing enough, the instructions that appear on your panel may be for a control on someone else’s – leading to plenty of frantic shouting.

Talking to Bob is always a pleasure, and interviewing him was likewise. He’s a man who knows his stuff and isn’t afraid to inject a little bit of humour into proceedings, and that hopefully comes across in the piece. Having played Spacehack, I can attest to both its difficulty and its brilliance and if anyone local builds their own – the hardware and software are both permissively licensed, naturally – I’d be up for a tournament.

The ZoomFloppy is a natural extension to the KryoFlux I reviewed back in Issue 131. Where the KryoFlux offers a means to connect old-fashioned floppy drives to a modern computer for archival-grade access, the ZoomFloppy is a little different: it’s designed specifically for Commodore devices. Its most common use, as the name suggests, is to provide an interface between a Commodore 1541/1571 floppy drive and a modern PC but it also offers the ability to talk to any Commodore-compatible serial device: printers, plotters, even modems. Better still, you can talk to these devices from directly within an emulator – I couldn’t help but grin when I loaded an Infocom game into the Vice emulator from the original floppy on an 1571 drive.

Finally, the Gizmo 2. I reviewed the original Gizmo in Issue 125 of Linux User & Developer, and was suitably impressed by its performance. The Gizmo 2, I’m pleased to say, blows its predecessor out of the water but isn’t without its own foibles. During my review, I ran into an issue in the firmware which prevented it from booting any device connected into its USB 3.0 ports. Although USB 2.0 worked fine, this had a negative effect on speed – and while the issue was still outstanding at the time of publication, I’m pleased to say a new BIOS has been released as a result of my feedback which fixes the problem and makes the Gizmo a great choice for anyone who needs x86 compatibility and impressive compute performance from a single-board computer.

All this, plus a bunch of stuff written by people who aren’t me, can be yours with a trip to your local supermarket, newsagent, or from the comfort of your own home via Zinio and similar digital distribution services.
