Retro to the core

      4 Comments on Retro to the core

There are some things that are hard to get your head around unless you can actually see them. Being a computer history fan I’ve often read of core memory but never quite got to grips with how it works. So one day recently I just thought, ‘the hell with it – I’ll go on eBay and buy some’. Which I… Read more »

Python on the PiDP

      No Comments on Python on the PiDP

I’m not really a C kind of person. And so when I finished building my PiDP kit, I immediately started thinking, ‘Wouldn’t it be nice to use all these switches and lights from Python?’ Because Python really is my kind of language. You can be properly expressive in it. And there’s not all that nasty business with make files. Fortunately,… Read more »

SIMH on the Raspberry Pi

      No Comments on SIMH on the Raspberry Pi

Installing the software for the PiDP, Oscar Vermeulen’s re-imagining of the PDP-8/I, couldn’t be easier. But that wasn’t going to stop me making life harder for myself. I mean, why do we play with machines like this? It’s to learn, to explore, to discover, to take things apart and occasionally to break them. I haven’t done that last one yet,… Read more »

Computing the ’60s – Raspberry Pi style

As soon as I heard of the PiDP I knew I would have to have one. Created by Oscar Vermeulen, whose KIM Uno kit I’d previously bought, it’s a brilliant recreation of a PDP-8/I using SIMH running on a Raspberry Pi. What’s more, it has loads of blinkenlights. So why did the kit sit in my office for eight months… Read more »

Forward to the past

This photo is just a teaser for a couple of forthcoming blog posts. Both of these are, in effect, glorified cases for the Raspberry Pi. And I know what you’re thinking … “kinda big, ain’t they?”. On top is the PiDP – Oscar Vermeulen’s recreation of a PDP-8/I. In this picture it’s in its not-quite-finished state. Below is a 1960… Read more »

PiDP: The next project

      No Comments on PiDP: The next project

Well, this is exciting. My PiDP kit has just arrived from Oscar Vermeulen. I couldn’t resist pealing back the protective cover on the acrylic front panel. It looks fantastic – and will be so much better when it has all the blinkenlights. I haven’t decided yet whether I will use one of the Raspberry Pi A boards I have lying… Read more »
