CRG | Why doesn't this A590 work with this Amiga 500 Plus? @CRG | Uploaded October 2023 | Updated October 2024, 7 hours ago.
When Richard reached out on the CRG discord looking for help with his supposedly good working A590 side car, well, its one thing I've never had the chance to work with until now so I was more than happy to do so.

A bit of an odd one because the A590 was sold as working and the Amiga itself certainly works fine, so why don't they work together?
