NeXTcube Turbo

NeXTcube Turbo is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand NeXTcube Turbo rather than just read about it. In short: The NeXTcube Turbo is a high-end workstation computer developed, manufactured and sold by NeXT. It superseded the earlier NeXTcube workstation and is housed in the same cube-shaped magnesium enclosure.

Key takeaways

NeXTcube Turbo belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NeXTcube Turbo to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NeXTcube Turbo from memory before moving on to harder problems.

Reference excerpt

The NeXTcube Turbo is a high-end workstation computer developed, manufactured and sold by NeXT. It superseded the earlier NeXTcube workstation and is housed in the same cube-shaped magnesium enclosure. It runs the NeXTSTEP operating system.

Hardware The NeXTcube Turbo is a development of the earlier NeXTcube. It differs from its predecessor in having a 33 MHz 68040 processor. The NeXTdimension board can also be used in the NeXTcube Turbo. There was also a very rare accelerator board known as the Nitro; between 5 and 20 are estimated to have been made. It increased the speed of a NeXTcube Turbo by replacing the standard 33 MHz processor with a 40 MHz one.

Specifications Display: 1120×832 17" grayscale MegaPixel Display Operating system: NeXTSTEP, OPENSTEP CPU: 33 MHz 68040 with integrated floating-point unit Digital signal processor: 25 MHz Motorola DSP56001 RAM: 16 MB, expandable to 128 MB (Four 72-pin SIMM slots) Floppy Drive: 2.88 MB (optional) Hard Drive: 400 MB, 1.4 GB or 2.8 GB SCSI drive Expansion: four NeXTbus slots (mainboard uses one slot) Size (H × W × D): 12" × 12" × 12"

Worked examples

Example 1 — a first encounter with NeXTcube Turbo

Start with the simplest possible case. Write down what NeXTcube Turbo claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to NeXTcube Turbo before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about NeXTcube Turbo ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of NeXTcube Turbo

In research: NeXTcube Turbo appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses NeXTcube Turbo in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: NeXTcube Turbo is common in secondary-school and first-year university syllabi. It links to neighbouring topics 68k-based computers, Computer-related introductions in 1992, Computer workstations, so understanding it makes those chapters shorter.
In everyday life: Look for NeXTcube Turbo outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is NeXTcube Turbo in simple terms?

Why does NeXTcube Turbo matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study NeXTcube Turbo?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
