PlayStation 2 models

PlayStation 2 models is a 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 PlayStation 2 models rather than just read about it. In short: Several models of the PlayStation 2 (PS2) video game console were produced from 2000 to 2013. Some PS2 revisions only change in their internal construction or implement cost-saving measures while others feature substantial external changes.

Key takeaways

PlayStation 2 models belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PlayStation 2 models to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PlayStation 2 models from memory before moving on to harder problems.

Reference excerpt

Several models of the PlayStation 2 (PS2) video game console were produced from 2000 to 2013. Some PS2 revisions only change in their internal construction or implement cost-saving measures while others feature substantial external changes. Each region receives a different model number; for example, slimline models produced from 2008 to 2013 were released in North America as SCPH-90001, in Australia as SCPH-90002, and in Hong Kong as SCPH-90006. The final digit is a region code with no bearing on the hardware; many games and DVDs are restricted to certain regions, and the system software displays in different languages. A total of 5 different models of the PS2 were produced during its lifespan. The PS2 is primarily differentiated between models with the original "fat" case design introduced in mid-to-late 2000 and the later "slimline" models introduced at the end of 2004. In 2010, a television incorporating a PS2 was introduced.

Original case design

Three of the original PS2 models (SCPH-10000, SCPH-15000 and SCPH-18000) were only sold in Japan and had a PCMCIA slot unlike all other models sold worldwide. The two PS2 launch models in Japan (SCPH-10000 and SCPH-15000) had no built-in DVD movie playback and instead relied on encrypted playback software that was copied to a memory card from an included CD-ROM (normally, the PS2 will only execute encrypted software from its memory card; see PS2 Independence Exploit); the later Japan-only PS2 models (SCPH-18000 and later) did eventually come with built-in DVD movie playback.

There was also the SCPH-3000x, 3500x, 37000, 3900x, and 500xx models, which were sold between 2000 and 2004 for all regions including North America and Europe. These models replaced the PCMCIA slot of previous Japan-only models with the expansion bay, which contained space for a 3.5" hard disk drive and a connector for the Network Adaptor. They also came with built-in DVD movie playback, unlike the initial two PS2 models in Japan. Early SCPH-3000x models produced from late 2000 to early 2001 had a substantially different internal structure than with earlier Japan-only revisions as well as subsequent revisions, featuring several interconnected printed circuit boards. In later SCPH-3000x models produced from 2001 to 2002 as well as the SCPH-3500x, everything except the power supply was unified onto one board. Some minor internal changes were made in SCPH-3000x(R) models produced from late 2001 to 2002, and the only difference between early and later SCPH-3000x(R) models is the orientation of the Power/Reset switch board connector, which was reversed in later revisions to prevent the use of no-solder modchips. These models also had a more reliable laser than with previous models. SCPH-3000x models sold between 2000 and 2002 also used either the initial version of the Graphics Synthesizer (GS) as found on the three Japan-only models or the revised, smaller version of the Graphics Synthesizer as found in the majority of PS2 consoles up until the SCPH-500xx models and some SCPH-700xx and SCPH-7500x models, depending on the time of manufacture. SCPH-37000 and SCPH-3900x included only minor revisions to the 2001–2002 SCPH-3000x(R) models.

Beginning with the SCPH-500xx models, the i.LINK port was removed, and a built-in infrared receiver was added in-between the Power/Reset and Eject buttons to allow for the use of a remote to control DVD playback without the need of a dedicated infrared receiver dongle as used on previous models, leaving both controller ports free from the external receiver. The console's mechanics controller (also known as the MechaCon) was also upgraded to use an ARM-based core (based on the ARM7TDMI) instead of a Sony-provided one that was used in earlier models. The standard color of the PS2 is matte black. Several different variations in color were produced in different quantities and regions, including ceramic white, light yellow, metallic blue (aqua), metallic silver, navy (star blue), opaque blue (astral blue), opaque black (midnight black), pearl white, Sakura purple, satin gold, satin silver, snow white, super red, transparent blue (ocean blue), and also Limited Edition color Pink, which was distributed in regions including Oceania and parts of Asia.

Worked examples

Example 1 — a first encounter with PlayStation 2 models

Start with the simplest possible case. Write down what PlayStation 2 models claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 PlayStation 2 models 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 PlayStation 2 models 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 PlayStation 2 models

In research: PlayStation 2 models appears in 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 PlayStation 2 models 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: PlayStation 2 models is common in secondary-school and first-year university syllabi. It links to neighbouring topics PlayStation 2, Sony consoles, Video game console revisions, so understanding it makes those chapters shorter.
In everyday life: Look for PlayStation 2 models 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.
