Macintosh IIci DayStar PowerCache P33 Upgrade

Published August 8, 2019

About This Video

In this video, I upgrade my Apple Macintosh IIci with a DayStar Digital PowerCache P33 68030 50MHz accelerator card, replacing the stock Macintosh IIci 32 KB Level 2 cache card with a significantly faster processor upgrade designed to boost classic Macintosh performance.

The DayStar Digital PowerCache series was one of the most respected Macintosh accelerator solutions of the late 1980s and early 1990s, giving vintage Apple systems substantially improved performance for productivity software, graphics applications, multitasking, and classic Macintosh gaming. The Macintosh IIci itself remains one of the most iconic and expandable 68k Macintosh computers Apple ever produced.

Alongside the DayStar PowerCache P33 installation, this video also showcases several modern retro computing upgrades including a SCSI2SD V5.1 solid-state storage replacement board and a BMOW Mac ROM-inator II Atom SIMM upgrade. The SCSI2SD replaces the original failing Apple 80 MB SCSI hard drive while the ROM-inator upgrade modernizes the Macintosh IIci experience with enhanced ROM functionality and boot options.

Also shown are close-up looks at the Macintosh IIci internals, the original Apple cache hardware, the DayStar accelerator card, installation process, and upgraded Macintosh hardware configuration.

Viewers drawn to vintage Apple computers, Macintosh IIci upgrades, DayStar Digital accelerator cards, 68k Macintosh systems, retro Apple hardware, SCSI2SD storage upgrades, BMOW ROM-inator products, and classic Macintosh restoration projects should feel right at home with this one. The Macintosh IIci remains one of the best platforms for exploring high-end vintage Mac performance upgrades.
