The issue opens with a FOReVER demoparty report featuring road adventures, a spontaneous 1K intro, and the party atmosphere. The technical section covers iterative division and QR codes on Z80, pixel plotting optimization, and fixed-tacts routines. Gasman details the creation of Megademica's 8-minute soundtrack: from the 'idea bytes' concept to data compression and compositional tricks. Also featured: the history of Forever party venues, experiments with asymmetric numeral systems, a review of DACs on Didaktik computers, and a tongue-in-cheek chronicle of how the Spectrum spawned AI.
