A New Lease of Life

I changed jobs about 18 months ago, and I’m already getting known as ‘that’ guy when it comes to fiddling with technology!

So, a colleague turned up at work with a laptop which had been given to him by a family member, after they’d bought a newer machine. He said it was running slowly and asked me if I’d have a look.

It seemed reasonably modern, probably about 7 or 8 years old. However it was running Windows 7, which I don’t really know my way around too well having not used Windows myself since the days of Windows 98 and Windows XP.

I was able to find out enough information to establish that the machine was slow because the hard drive was struggling with multiple read errors. My colleague also said it crashed a lot and some files had disappeared. A quick boot into Linux with my trusty USB stick (which is always in my pocket!) confirmed the SMART data on the drive showed it was unserviceable. So I gave him the bad news and suggested it needed a replacement disk.

We discussed use cases to decide on a size, and he ended up ordering a small solid state disk for about £25 including delivery. I showed him which screws to undo to swap the drive out and gave him a USB installer for Ubuntu, explaining that I didn’t have a way to get him a copy of Windows and he’d need to talk to someone else about that.

The new drive duly arrived, and my colleague was able to fit the disk and install Ubuntu from scratch using the USB stick I’d lent him. My colleague would be the first to say he’s not very technical, so I think credit is due to the GNU/Linux community for making Linux so easy to use these days.

Even more exciting (to me!) is that my colleague has absolutely no plans to go back to Windows. He’s found software to do everything he wants, says the machine is faster than it ever was and is happy to have an up to date and modern laptop for an outlay of £25.

I really enjoy helping people to try Linux and realise that when they thought they needed a new computer, they often don’t. Machines are saved from landfill, and resources aren’t wasted on an unnecessary new machine. Everyone wins!

If you’d like to try running Linux on your computer, I’d recommend trying Ubuntu because it is well thought out and works on most things with ease. You can download it for free from this link.

The RC2014 Computer

While at Liverpool Makefest last June, I bought myself a kit to build an RC2014 Z80-based computer.

The kit was very well made, with high quality circuit boards which accepted solder very easily, along with sufficient documentation to make the whole building process smooth and enjoyable.

I found the process quite educational too, as the design of the kit splits out the various functions of a computer into separate boards which then plug into a backplane with a common bus linking the parts together. It was good to see how the CPU, ROM, RAM, Clock and I/O all work together to make a functional microcomputer.

I was able to talk to the RC2014 from another computer over a serial connection, but I found I got the real ‘retro’ feel when I added the RC2014 ‘video card’ – which is a serial terminal based on a Raspberry Pi Zero. This meant I could plug my creation into a monitor and keyboard without the need for a separate computer, making the whole thing into a self-contained 8-bit microcomputer.

I also added an I/O board of LEDs and switches so I could interact with the computer without the need for a monitor or keyboard.
