Apple Macintosh LC 475

Apple Macintosh LC 475 was introduced in 21 October 1993 and brought 68040-class performance to the compact low-cost LC enclosure. It used a Motorola 68LC040 at 25 MHz with 4MB standard; expandable to 36MB. 68LC040 processor omitted the floating-point unit but greatly improved integer speed.

Its strong price-to-performance ratio led to many LC and Performa variants and made it a popular education and home Macintosh.

Notable Features

• 68LC040 processor omitted the floating-point unit but greatly improved integer speed.
• Compact case retained LC III expansion and memory compatibility.
• Optional full 68040 upgrades added hardware floating point.

Historical Significance

• Its strong price-to-performance ratio led to many LC and Performa variants and made it a popular education and home Macintosh.
• Its place in the range reflects Apple's progression from the original compact Macintosh toward broader professional, educational and portable markets.

Collector’s Notes

• PRAM-battery leakage and brittle drive bezels are common, while full-68040 upgrades are sought after
• Original keyboards, mice, storage devices and model-specific accessories help document a complete period configuration.
