Images depicting the upgrade process were taken in 2003. I took the pictures to illustrate how to install the Sonnet Presto Plus in a Macintosh Color Classic. My apologies for the image quality. I used a 2-megapixel Sony camera. Sonnet no longer manufactures the Sonnet Presto Plus. Before they discontinued the product, their website stated the following:

The Sonnet Presto™ Plus multi-functional card brings essential hardware features to your Macintosh Color Classic, LC, or Performa series computer. With the Presto Plus you finally have the processing power and memory expansion capabilities to run web browsers, large applications, and educational programs. The built-in Ethernet port is perfect for schools and individuals wanting to hook up to the Internet through an Ethernet network.

The Presto Plus features a 66/33 Mhz 68040 processor, delivering up to 650% overall speed improvement and can be configured with an optional FPU (math coprocessor) for faster mathematical calculations. The onboard RAM expansion SIMM slot includes a 32MB SIMM, adding to the existing RAM in your system.

The Sonnet Presto Plus is the only 68040 processor upgrade card that allows you to run virtual memory, RAM Doubler, 68040-based applications and games, and Mac OS 8.1.


The Sonnet Presto Plus card is a collector's item. I consider it to be rare. Even though I paid $99 for it back 2003, I could get a lot more for it if I sold it on eBay today. Vectromania
