NMS-8250

NMS-8250 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 NMS-8250 rather than just read about it. In short: Philips NMS 8250, (NMS is short for "New Media Systems") was a professional MSX2 home computer for the high end market, with a built in floppy disk drive in a "pizza box" configuration, released in 1986. The machine was in fact manufactured by Sanyo and it is basically the MPC-25FS with a different color.

Key takeaways

NMS-8250 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 NMS-8250 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NMS-8250 from memory before moving on to harder problems.

Reference excerpt

Philips NMS 8250, (NMS is short for "New Media Systems") was a professional MSX2 home computer for the high end market, with a built in floppy disk drive in a "pizza box" configuration, released in 1986. The machine was in fact manufactured by Sanyo and it is basically the MPC-25FS with a different color. It featured professional video output possibilities, such as SCART for a better picture quality, and a detachable keyboard. Three regional models were produced:

NMS 8250/00 for the Dutch and Belgian markets with a QWERTY keyboard; NMS 8250/16 for the Spanish market with a QWERTY keyboard with ñ key; NMS 8250/19 for the French market with a AZERTY keyboard.

The Philips NMS 8255 is a similar machine, but has with two disc drives instead of one.

Specifications The Philips NMS 8250/8255 have the following specifications:

CPU: Zilog Z80A with a clock speed of 3,56 MHz ROM: 64 kB (MSX 2: 48 kB, Disk BASIC: 16 kB) RAM: 256 kB VRAM: 128 kB Display: Yamaha V9938 (80×24, 40×24 and 32×24 character text in four colors - two foreground colors and two background colors; resolution of 512×212 pixels (with 16 from 512 colors) or 256×212 (with 256 from 512 colors). Controller chip: MSX-Engine (S-3527, real-time clock with rechargeable battery). Sound: PSG (S-3527, 3 sound channels, one noise channel) Floppy drive: 3.5'', 720 kB double sided. Connectors: mains cable, RF-output, CVBS monitor, luminance video output connector (for monochrome monitors), tulip (RCA) connector audio output, SCART audio/video-output using RGB, data recorder, Centronics compatible parallel printer port, detachable keyboard connector, two joysticks, two cartridge slots.

Worked examples

Example 1 — a first encounter with NMS-8250

Start with the simplest possible case. Write down what NMS-8250 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 NMS-8250 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 NMS-8250 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 NMS-8250

In research: NMS-8250 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 NMS-8250 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: NMS-8250 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, MSX2 microcomputer, Philips products, so understanding it makes those chapters shorter.
In everyday life: Look for NMS-8250 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.
