Byte Power Spring 1987

Decision Maker

Duo-Voice (Beep)

A clever two-voice BEEP music engine that rapidly alternates between voices stored as raw byte data in RAM, simulating polyphony with sentinel values for rests and end-of-tune.

EASYprint Word Processor

A tape-based text editor.

INKEY$

An eight-byte machine-code routine lets you scan any keyboard half-row for simultaneous keypresses, complete with a tape-save option and interactive demo.

Mister Butterfly

The Qualifier

Enter your down payment, monthly budget, interest rate, and loan term to instantly calculate the maximum home price you can afford.

Tri-Voice (Beep)

A clever BASIC scheduler interleaves three BEEP voices at high speed to fake polyphony, reading note-and-duration byte pairs straight from a memory-resident music block.

Tycoon

A ten-level oil-drilling game that switches UDG sets via direct POKEs, detects its host machine at runtime, and lets mines blow up your pipes underground.
