A compact 34-byte machine code routine scans your system's memory map and reports what's installed — all launched from a tiny BASIC loader.
An interactive pie chart generator that draws trigonometric slices from user-supplied percentages, then lets you add labels and a centered title.
A self-building proportional text engine that compresses ROM fonts on the fly and patches the LPRINT channel to render neatly spaced characters on screen.
A compact RLE graphics manager with machine code encode, decode, invert, and wipe routines lets you store, load, and manipulate compressed screen images from cassette.
A ROM diagnostic tool verifies memory integrity and floating-point accuracy using byte-sum checksums and deliberate arithmetic rounding-error accumulation tests.
A memory-poking BASIC renumberer lets you reassign a chosen range of program lines to a new start number and step, all without any machine code.
Eight BASIC scroll routines — up, down, left, right, each with and without wrap — all driven by clever single-string manipulation of a 704-character display buffer.
An interactive AY sound chip programmer lets you set every register, build multi-step sequences, and play back timed soundscapes — all from a menu-driven interface.
A self-installing Z80 sprite engine with checksum protection loads into high RAM, controllable with a single USR call or a POKE to disable it.
