Commentary on machine code and assembly language articles in Vancouver TSUG newsletter: V. Lee’s ongoing TS2068 assembly language series, and Wilf Rigter’s techniques for speeding up the ZX-81/TS1000 by modifying display routines—achieving greater gains than the roughly 15% boost from a 4MHz clock speed increase. Also discusses hardware modification trends across newsletters (shift toward QL mods), and highlights Donald Lambert (CRAGIST) building a minimal ZX-81 short board (ROM, RAM, EPROM only, no ULA or keyboard) used as a kite-camera controller.
