The Quadra 900 was one of the most powerful Macintosh models Apple sold at the time, along with its little brother (and my personal grail of vintage Macs) – the Quadra 700. The Quadra 900 was a beast in its day – expandable up to 256 MB of memory, five NuBus expansion slots and one PDS (processor direct slot) and could be ordered with a hard drive as large as 400 MB.īoth used the Motorola 68040 processor, which would be the most powerful and last Motorola processor used by Apple prior to the PowerPC transition.

The Quadra 900 was replaced by the Quadra 950 a year later in 1992, but both were supported until Mac OS 8.1. The Quadra 900/950 case (which is perhaps my favorite pre-Jobs Return case design) was also used for the Apple Workgroup Server 9150.Īs it turns out, Macintosh.js is based on Basilisk II with some modifications made. The installation procedure for Macintosh.js is similar to that of Mini vMac (at least on a Mac.) You simply download the package, expand it and drop the Macintosh.js application in your Applications folder. Then you will have a fully-functional Mac OS 8 emulator on your computer. While Macintosh.js is just as easy to install as Mini vMac, there are some big differences.
