This week on the blog: Finishing my tour of the base ZX Spectrum hardware by looking at the memory mapper in the 128K version, with a nod to the +2 and +3 successors. I'm not totally done with the platform, but now that I've looked closely at everything I saw in my initial tour, I'm shifting gears for a bit before I return. https://bumbershootsoft.wordpress.com/2026/08/15/zx-spectrum-system-tour-memory-mapping/ #retrocomputing #zxspectrum
