If you were around in the mid-to-late 1980s, computers were less like a commodity and more like being part of a quiet revolution. I spent untold hours at that time pushing the Apple Macintosh for desktop publishing (DTP). With PageMaker, Illustrator, and an Apple LaserWriter, we spent days convincing printing businesses and ad agencies and design studios that paste-ups were fossils. I clearly remembered competing with the Windows guys doing ‘live’ demos with just the cumbersome Apple Mouse, drawing complex pictures with the very first version of Illustrator, and winning business with just that. But as groundbreaking as System 6 and early Mac OS were, in the background was a fine-grained, cooperative multitasking operating system. If one app decided to crash or hoard memory, your entire session disappeared into a terrible bomb error popup. We liked the Mac, but those of us who cared about system architecture understood it needed an industrial strength foundation. ## The Black Cube at Alexandra Road Fast forward to about 1989. Steve Jobs had long since left Apple to create NeXT Computer, pursuing an absolute idea of what an academic and workstation computer should be. At the time, Canon had invested heavily in NeXT, perhaps one hundred million dollars, and acquired regional distribution rights. So I found myself heading into Canon’s showroom on Alexandra Road here in Singapore, anxious to get my hands on a machine that felt like science fiction: the original NeXT Computer (the NeXT Cube). Seeing the 12-inch die-cast magnesium cube in person felt “electric.” Unlike the beige plastic boxes that clutter most office desks, the NeXT Cube was a thing of matte black beauty, sandwiched by the NeXT display, a magneto-optical drive, and an onboard digital signal processor (DSP). What truly stopped me cold was the operating system: NeXTSTEP. It not only adopted the GUI paradigm, but it also refined it. NeXT took BSD Unix, layered it on top of a Mach microkernel, wrapped it all up in an object-oriented Objective-C runtime, and drew the desktop with Display PostScript. The interface was sharp, responsive, and rock solid. You could whip up code in a Unix terminal while seamlessly dragging UI widgets within Interface Builder without missing a beat. It was years ahead of its time. ## When NeXT Became Apple’s Future My personal technical route back in the 90s delved deep into Unix. For years, I worked side-by-side with FreeBSD to build hardened cybersecurity solutions and high-throughput email security appliances. Day after day of configuring kernels, IP stacks, and mail daemons on Unix gives you an appreciation for true preemptive multitasking, sound protected memory, and explicit architectural modularity. Meanwhile, back in Cupertino, Apple was struggling to upgrade its ancient System 7 & System 8 lineage. Apple needed a new OS badly. Apple bought NeXT in late 1996, bringing Steve Jobs and the entire NeXTSTEP ecosystem back home. As a BSD developer, it was really satisfying to watch that transition. NeXTSTEP was built on the Mach kernel and the fundamental components of FreeBSD and NetBSD. Apple’s open-source core was rebranded as Darwin. Objective-C with the NeXT frameworks was renamed Cocoa. The slick NeXT Workspace evolved into the Aqua desktop interface of Mac OS X (now macOS). Every time you open a modern Mac terminal, drag a window in macOS, or publish an iOS app built on Foundation and AppKit frameworks, you’re directly engaging with the architectural DNA that was inherited from that black magnesium cube, and before that, the BSD ancestor itself. ## History Repeats: The “Previous” Emulator Fans of antique electronics will know how notoriously difficult it is to keep original NeXT hardware alive today. Capacitors leak, power supplies break, and magneto-optical drives are getting harder to find. I came upon an open-source emulator sometime ago called, rather hilariously, [Previous](https://previous.nextcommunity.net/?mwire) . Based on the Hatari Atari emulator and WinUAE’s emulation core for the Motorola 68000, “Previous” is made to emulate original NeXT hardware down to the peripheral level. It emulates the NeXTstation and NeXT Cube models exactly, as well as its DSP processors and SCSI controllers, and supports the 68030 and 68040 architectures. [Screenshot: Previous Emulator site—quite a nice look if you ask me] Fair warning: it isn’t a one-click affair to set it up and requires a moderate amount of technical prowess. You need to grab dumped ROM images from a real NeXT machine, create and partition a virtual disk image to correctly reside on the emulated SCSI bus, find valid NeXTSTEP install media (NeXTSTEP 3.3 for instance), and set up virtual network bridging if you want the guest workstation to talk to your local LAN. Once you get past that initial configuration obstacle, it’s pure joy to watch NeXTSTEP boot up on a contemporary workstation. Turning on Interface Builder, fiddling with the DSP audio examples, and flipping through NeXT’s classic multi-column file browser feels like stepping into a time capsule. Most importantly, it reminds us of the staying power of smart software engineering. The ideas that sprang from that black cube nearly 40 years ago never disappeared; they developed and matured, and today they continue to fuel millions of creative and computing operations around the world. ###
