Let's have a look at the Inves Spectrum+, a rare Sinclair ZX Spectrum+ clone from Spain. As usual, we'll open it up and see what's inside, and we'll try to fix it up so it runs as good as new.

I managed to get it up and running but it had a strange greenish tint to the video out. I tried a bunch of things, but didn't manage to make it go away. Strange!

We'll wrap up the restoration and we'll have a close look at the tiny technical differences with the Sinclair ZX Spectrum+ in the next part.
