• A 4-bit CPU


    I’ve been insanely busy over the last few months. The human malware crisis has kept me busy at work and I’ve got so many projects on the go that I don’t know whether I’m coming or going half the time… so I thought I’d add another couple of projects to the pile to keep things […]


  • Evil genius control desk


    So I’ve been asked to build, what’s being called, “the evil genius control desk”. In reality it’s a studio lighting and audio control solution that has some unique features.  The studio space in question is divided into several areas and split over two levels.

The one thing I’m pleased with is that by replacing the relatively slow (in terms of access speed) EPROM […]


  • Acorn System 1 Memory Board and Dataman programmer update


    Last week I’d had enough of that Dataman programmer. It would sometimes work but more often that not Windows would fail to recognise the programmer. I’d tried it on Windows XP and three different Windows 10 machines (one was a brand new out the box machine) and it was always the same. So I sent […]


  • Acorn System 1 progress and Dataman programmer


    I’m sort or regretting buying this Dataman programmer. I need to spend a lot more time trying to figure out exactly what’s going on with it, but assuming my unit doesn’t have some weird intermittent fault, then the quality of the software; specifically the USB driver sucks. I’ve tried this programmer now in three different machines; […]
