PC Weasel 2000

PC Weasel 2000 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 PC Weasel 2000 rather than just read about it. In short: PC Weasel 2000 was a line of graphics cards designed by Middle Digital Incorporated (Herb Peyerl and Jonathan Levine) which output to a serial port instead of a monitor. This allows servers using PC hardware with conventional BIOSes or operating systems lacking serial capability to be administered remotely.

Key takeaways

PC Weasel 2000 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PC Weasel 2000 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PC Weasel 2000 from memory before moving on to harder problems.

Reference excerpt

PC Weasel 2000 was a line of graphics cards designed by Middle Digital Incorporated (Herb Peyerl and Jonathan Levine) which output to a serial port instead of a monitor. This allows servers using PC hardware with conventional BIOSes or operating systems lacking serial capability to be administered remotely. The product was introduced in 1999 and began shipping January 20, 2000. PCI and ISA models are available. The PC Weasel is also connected to a PS/2-compatible keyboard port and effectively emulates a keyboard by converting characters obtained from the serial port to keyboard scancodes. The card may also be connected to the reset pins of the motherboard and reboot the machine on command. The PC Weasel is an open-source product. Every purchaser of the board is granted a license for the card's onboard microcontroller. The microcode, stored in flash memory, is modifiable using a gcc-based toolchain.

Worked examples

Example 1 — a first encounter with PC Weasel 2000

Start with the simplest possible case. Write down what PC Weasel 2000 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 PC Weasel 2000 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 PC Weasel 2000 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 PC Weasel 2000

In research: PC Weasel 2000 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 PC Weasel 2000 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: PC Weasel 2000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Graphics cards, Out-of-band management, System administration, so understanding it makes those chapters shorter.
In everyday life: Look for PC Weasel 2000 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.
