Welcome to the Egghead homepage

My name is Jonathan Cauldwell and back in the late 1980s I began writing games for the ZX Spectrum computer.  Several were published, the most famous of which were probably Egghead and Egghead to the Rescue, which appeared on Crash powertapes in 1990.  The ZX Spectrum died as a mainstream games machine in 1993 but if you owned one of these machines in the years leading up to that time, the chances are that you've played at least one of my early games.  I can only apologise for that and hope that the experience didn't scar you for life...

I am still producing software for the ZX81 and Spectrum, having churned out titles over a period of three decades to become the most prolific Spectrum developer of all time with over fifty titles.

On this site you'll be able to find out more about the games I wrote back in the day, what I worked on after that, as well as maybe learning how to create your own games for the machine that kick-started the British games industry.  You can find some of my games on here as free emulator downloads.  Physical cassette copies are available over at Cronosoft and if you want to play some of them on your mobile you can check out Jonathan Needle's Spectaculator page.

I am still supporting Multi-Platform Arcade Game Designer and to a lesser extent Arcade Game Designer.  A new version of AGD is currently in the pipeline.  For those who are unaware, MPAGD is a powerful Windows tool that enables the user to easily create new games for a variety of 8-bit computers including the ZX Spectrum, MSX, Amstrad CPC, BBC and Dragon 32/64.  No previous programming experience is necessary, it is simple to pick up and an excellent way for you or your children to learn to code.

If you would like to support my work head over to My New Patreon Page where for a small subscription you will get the latest updates, exclusive content and access to software before anyone else.

My YouTube channel is here, or try my page at Hackaday.

Note that I do not have an account on Twitter.

I have a few retrogaming sticker, mug and T-shirt designs here.
