Mac Plus Monitor Latest Mac Technology

The Apple II and IBM PC computer lines were “cloned” by other manufacturers who had reverse-engineered the minimal amount of firmware in the computers’ ROM chips and subsequently legally produced computers that would run the same software.

The Mac Plus has up to 4 Megs of RAM, and an internal 800K floppy drive. Most are tan (beige), later models were “platinum” (off-white with grey keys). This one is pictured with an optional external 800K drive, the extended keyboard, and mouse. Some units with faded colors or uneven fading are offered at a discount. The 128K and 512K look very similar but have different connectors than the Plus for printer and modem; and there are variations in labeling.

Mac Plus, tan, little to slight fading, with 4 Megs RAM, 800K floppy: ask for price, state cosmetic condition, note if you want a keyboard and mouse.

Mac 512K’s or 512KE’s hardly ever come up in surplus so it’s hard to get more.
Mac SE FDHD or SuperDrive: The SE series of Macs have up to 4MB of memory and a 9-inch diagonal black and white CRT. For years, these SE’s were relatively common as surplus. Today in 2005, they are getting hard to find, and many of them have cosmetic fading (they are turning yellow). And, at 20 years or so, their original hard drives are just wearing out.

Mac SE, 4 Megs RAM, 1-800K floppy, no kbdmouse: ask if available and state desired cosmetic condition.

SE FDHD (super drive), 4 Megs Ram, 1.4 floppy, no kbdmouse: ask if available and state cosmetic condition.

Mac SE/30 models: The Mac SE/30 is a prized “compact Mac” system, as it will support a relatively large amount of memory with eight 30-pin SIMMS. There are also a number of expansion cards for the SE/30 for Ethernet networking and for external video monitors. Some people use them as printer servers; some just enjoy upgrading and modifying them, or using them as they are.

Mac SE/30, 8 Megs RAM, HD (see below), 1.4M floppy, no kbd or mouse.

Mac Classic and Color Classic (and II) models: Classic and Classic II systems are available; some units have some color fading. Color Classics, with their color CRT’s, are even harder to find.

Help to choose your monitor

Making the right choice in a computer display or monitor is an important part of involving yourself in today’s web-browsing and multi-media technology. Right now, you are viewing this in a computer monitor (unless you’ve had someone print it for you and you’re reading it on paper because your monitor made it completely unreadable) and how it appears to you depends entirely on the quality of your display.

Monitors

What are the differences between an LCD screen and CRT monitors?

LCD screens are the current trendy looking; flat screen displays that are now sold with practically all bundles, whereas CRT screens are bulky older style technology. Apart from the space saving that the flat screen LCD (Liquid Crystal Display) offers, it also generates very little heat and radiation, uses considerably less power and is less reflective. LCD screens present excellent image quality. CRT (Cathode Ray Tube) monitors on the other hand, occupy a lot more space on your desktop, do generate heat and use more power and usually have a curved screen (although flat screen CRT monitors are available).

From a display point of view, the major difference between the two lies in how the image is created, and the resolution that the screen can accommodate. Each pixel in a LCD screen is produced by a tiny cell containing a layer of liquid crystals that bend light in response to electric energy. While they can be clearer than CRT screens, they are limited by only one optimal resolution. Setting the screen at a higher than optimal resolution reduces the overall screen image, and at a lower one causes the screen image to appear “pixelated”.

A CRT screen creates its image through cathode ray emissions striking the phosphorous lining on the back of the tube glass. It offers more detail in images and colour at higher resolutions.

One other difference to note is the display size. Display size is the diagonal measurement across the screen. A 17 inch (these have not been metricated yet) display is measured from one corner diagonally to its opposite. In a LCD display, this covers the entire framed display, but in a CRT monitor, the display image is usually 8%-10% smaller than the framed screen area, which means a 17″ CRT monitor has to have a bigger framed screen than a LCD.

Compatibility

There are possibly two issues of compatibility to consider. One is the compatibility of the screen with your workspace and the work you want it to do. If you have a small space, then the slim features of the LCD will be a major part of your decision. It is better to buy an all-digital screen rather than one that plugs into a standard video card (which is analogue) and then translate an analogue signal to digital. An all-digital display will offer brighter images. Compatibility with your computer’s video card is another consideration. You need to be sure that the video card you have in your computer will provide the screen resolution your require from your monitor and match the refresh rate.

Technical considerations

Dot Pitch. This is the distance between the same colour dots in any direction on a display. A smaller dot pitch enables easier reading of characters and better colour clarity. The maximum dot pitch you should consider for high quality graphics and text is .28 for a 17″ monitor and .31 for a 21″ monitor.

Screen resolution. The number of pixels a screen displays determines the resolution. A resolution of 1024 x 768 has 1024 pixels in the horizontal plane, and 768 in the vertical. The higher the resolution, the more detail is displayed. Be sure that your video card matches the resolution you require.

Refresh rate. This is the frequency at which the screen image is being refreshed to avoid flicker. A vertical refresh rate of 75 HZ (cycles per second) delivers a flicker-free environment and will reduce eyestrain and fatigue.

Cost

Of course it all comes down to what you can afford. But a good quality display is a good investment in your work environment. CRT monitors can be bought very cheaply. Digital LCDs can become very expensive. Manufacturers are now offering displays with inbuilt television receivers and speaker systems than can enhance your overall environment and improve the flexibility of your purchase. Ultimately, it depends on what you want to see on your desk as much as what youn want to see on your monitor. You can spend as little as $200.00 or well over $2,000 and you can do it all online.

Bar Code Scanners – Know the Features

Barcode Scanners are hand-held or stationary devices used for capturing information from barcodes. A barcode scanner consists of a code reader and a decoder. These devices are connected to a computer through compatible ports

The earliest, most basic and cheapest barcode scanners consisted of a fixed light and a single photosensor. Modern barcode scanners have polygonal mirrors and use laser scanning technology. Laser barcode printers have the advantage of reading barcodes from any angle.

Barcode scanners are available in different varieties like hand-held, hands-free, wearable, rugged, scan engines, laser and digital. Pen-wand scanners are the simplest and most portable type of such devices. They have to be kept in direct contact with the barcode and held at a precise angle to interpret the barcodes. Modern day digital cameras have enough resolution to capture both 1D and 2D barcodes.
Barcode scanners can be distinguished as follows:
LED scanner: Also referred to as CCD scanners, even though the CCD is in fact the photo imaging sensor, not the light source.
Laser scanner: More expensive than LED scanners but are generally capable of longer maximum scanning distances.
Imager scanner: These scanners take an image of the linear barcode, generally more rugged as they have no moving parts.
2D Imaging scanner: These scanners take a 2D image of the barcode as in a camera and can be used to scan 2D barcode types such as Datamatrix as well as the more common linear barcode types.
Handheld scanner: With a handle and typically a trigger button for switching on the light source.
Pen scanner (or wand scanner): a pen-shaped scanner that is swiped.
Stationary scanner: Wall- or table-mounted scanners that the barcode is passed under or beside. These are commonly found at the checkout counters of supermarkets and other retailers.
Fixed position scanner: An industrial barcode reader used to identify products during manufacture or logistics. Most often used on conveyer tracks to identify cartons or pallets which need to be routed to another process or shipping location.
PDA scanner: A PDA with a built-in barcode reader.

The latest in barcode scanner technology is mobile barcode scanners which use color code and mCode (new two-dimensional code format) to scan barcodes.

General purpose barcode scanners are used at checkout counters and hospitals. These are also used to process identification documents. Certain other kinds of scanners, like rugged scanners, are used in harsh or extreme conditions. Of the different barcode scanners, laser scanners and camera scanners are widely used these days. Camera scanners scan and capture the barcode images, which are then processed by sophisticated image techniques to decode the barcode.

Barcode scanners have increased the speed of data retrieval and data processing. They have become a mainstay in commercial establishments, libraries, counters, and virtually at any point-of-sale.

The benefits of barcode scanners are many. It greatly helps you organize your inventory, monitor the movement of goods, and ensure the security of your premises. Bar Code technology is helping enterprises worldwide streamline their business and control costs at the same time.

Choosing a right barcode scanner is an essential step for better inventory management and customer service.

Barcode readers come in different forms, sizes and prices. Their prices range from $50 to several thousands depending on the features, built, durability etc.

However, before purchasing a laser or CCD scanner, define your requirements:
The type of environment where you are going to use the scanner
Consider the portability factor
The symbology you plan to follow
The average scanning range

Choose a credible and reliable company. Go for a bar code scanner which has proved its usability. POS Components has made it its goal to provide the customers with the right equipment, from the right manufacturer, and at the right price!
