Description :

We're holding a special Retro Computer Festival weekend as part of our Computing on the Move season celebrating the portable computer. Portable computing is ubiquitous now - laptops are everywhere and a modern smartphone can out perform a 70s mainframe. The first commercial portable computer - the IBM 5100 from 1975 - weighed 24kg and still needed to be plugged into the mains. That's heavier than 200 iPhone 5s!

We're inviting collectors and portable computer enthusiasts to come show us their favourite machines, tell us about their history and demonstrate what they're capable of - expect everything from tiny pocket computers to huge luggables, and everything else in between. And of course, we'll be getting some rare and unusual portable machines on display from the museum's own collection!

Watch this space - we'll be updating this page with the news from the exhibitors regularly and tell you more about what you'll see. The exhibits might be small - but the event won't be!

Would you like to exhibit? Drop Tony a line on tony@computinghistory.org.uk for more information.

Exhibitors

Alex Brown

When it comes to portables, there are few companies more iconic than Psion. From the original Organiser through to the iconic Series 3a and Series 5mx, Psion repeatedly created machines that people loved to use, and now look back on with fondness. In a sidequest-gone-wrong, Alex has spent the past 6 years diving deep into the architecture of these machines, developing new hardware and software, and posting his findings online. He's amassed a sizeable collection of Psion handhelds and laptops, which he'll be bringing to the Portable Computer Festival. He'll also be showing off the PsiDrive, a new USB drive for using Psion SSDs on modern computers.

All Tony wanted back in 1982 was to be able to have a computer that let him write games on the long bus journey to school - easier said the done! See the options that would have been available to him at the time - from tiny Sharp pocket computers to battery powered Newbrains. Plus a whole bunch of other unique and exotic portables from his collection - and maybe even a portable Dragon!

"When I was told we where doing a portable version of retrofest, I thought excellent my back will like this one (and Pete will look less in pain). Then I remembered in the 80s portable meant, it has a handle. So I'll be bring portables big and small, and yes I will be using a different meaning of portable for unix this time."

John Newcombe - @GlassTTY

John will bringing a selection of mainstream handheld and portable computers with an emphasis on early modems and communications. Come and log on remotely to a PDP11 with everything from a Psion II to a Amstrad PPC or book a holiday and check your stocks and shares with an Apple IIc. If that's a little too business like for you, why not dial in to a remote mini computer and play Colossal Cave Adventure.

Transportable. Luggable. Laptop? The development of mobile business computers.

Amber screens are the best screens! I'll be exhibiting a sellection of portables from the late 80s that have amber coloured displays. CRTs and gas plasmas are in, batteries are most definitely out.

Redefining the modern world of portable, these machines are bigger than your Mum's sewing machine and you definitely wouldn't want them on your lap
