The Casio ML-88 is a classic, multi-functional vintage electronic melody calculator and digital clock released by Casio around 1983–1985.

Part of Casio's legendary era of "musical" office equipment, it is highly sought after by retro tech collectors today for its unique musical keypad capabilities and packed feature set

• Musical Keypad: The number keys 1 through 7 double as musical notes (Do, Re, Mi, Fa, So, La, Ti), allowing you to actively play melodies directly on the calculator keypad. 
• Pre-programmed Melodies: Includes three distinct musical alarms/melodies, including "Drilling Slide", "Tremurai", and "Moments Music Code Number Three". 
• Perpetual Calendar: Features a built-in calendar capable of tracking dates from 1901 to 2099 without requiring adjustments for leap years. 
• Timekeeping & Dual Alarms: Includes a digital clock with AM/PM indicators and day-of-the-week tracking, alongside two independent alarms. 
• Stopwatch & Timer: Features a precision countdown timer and a stopwatch with lap time functionality that tracks down to tenths of a second for up to 23 hours, 59 minutes, and 59 seconds. 
• Mathematical Constraints: Unlike some sister models of its era (like the ML-831), the ML-88 lacks a square root (\(\sqrt{}\)) function and does not include the famous Invaders number game found on the MG-880
