We build devices that bring your vintage computers into the 21st century


I'm Diego Parrilla, a Software Engineer who began exploring computers in the '80s as a teenager. Now in my fifties, my passion has transformed into creating modern equipment for retro computers. My aim is to infuse classic computers with the convenience and feel of modern devices, allowing us to relive the enchantment of the past with today's technology.

At SidecarTridge, our mission is to enhance the functionality of retro computers without compromising the authenticity of the experience. In 2023, we launched our inaugural hardware product: the SidecarTridge Multi-device for Atari ST series computers. This device has been a delightful surprise and was very well received within the Atari communities.

Today, we are committed to continuously innovating and developing new gadgets. There is no greater reward in my engineering career than seeing our products bring joy and renewed functionality to enthusiasts around the world!
