Macintosh Performa 450

Apple’s Macintosh Performa 450 was a personal computer that was designed, manufactured, and sold by the company in 1993 as part of their Macintosh Performa series. On April 12th of that year, the computer was introduced to the market with a starting price of $1,800.

The Performa 450 was equipped with a 25 MHz Motorola 68030 processor, a Motorola 68882 FPU coprocessor, 4 MB of RAM, a 120 MB hard drive, and a 1.44 MB floppy drive. These specs may seem lackluster compared to today’s standards, but at the time, they were considered top-of-the-line.

Unfortunately, the Macintosh Performa 450 was discontinued on November 1st, 1993. It’s been 30 years since its release and it’s hard to believe that this once cutting-edge computer is now a relic of the past.

While the Performa 450 may not be in production anymore, it’s still an important piece of Apple’s history and a reminder of how far technology has come. Today, we take for granted the advancements in processors, memory, and storage that have made our current devices so powerful and efficient. The Macintosh Performa 450 may be long gone, but it will always hold a special place in the hearts of Apple enthusiasts and tech enthusiasts alike.
