I started this post with a vague feeling that I needed to apologise about recent posts which included far too much detail.

However, on reflection, I’m going to stick with the science. If it’s not your scene then feel free to skip the boring bits. I’d like to think I’d keep all my readers with my witty observations on oscilloscope screenshots, but if I lose 99% of my readers, if 1% learn something useful, if I encourage 1 child to program then I think I’ve achieved something.

Finally, a request. I’ve not enabled comments yet. If you wander across this site, please tweet me, especially if you have any tips to help me repair my Spectrum or know of reliable suppliers of ancient chips.
