New video is out!

Mail has been piling up so time to rip open some packages and take a look at a mix of smaller items to pimp some of my existing gear as well as a new acquisition or two.

Oh! The ZX81 is celebrating its 45th anniversary today 🎂

It was the first computer my father ever bought. I was fascinated to watch him type on the keyboard and see things appear on the TV screen 🤩

Like a clock with moving hands! 🕓

Forty-five years ago today, Clive Sinclair introduced the ZX81. It wasn’t the first computer that I’d used, but it was the first that I could call my own.

The first video is online, the Scandinavian Retro peertube channel is a go!

In the first episode of Scandinavian Retro I explain what this peertube channel is about, do a quick tour around the new retro room, we look at a number of items that came in the mail and do a quick test of two of those items: the Amstrad CPC 464 and the 6128.
