European Stars and Stripes (Newspaper) - August 19, 1990, Darmstadt, Hesse                                Home front what you see depends on the Jerry Kidder finally after Many false starts i have purchased the replacement for my old Commodore 64. It took  searching and question asking i de.  my needs looked at the available products and took the dive. Since  started our journey into the world of personal computers  have covered the contents of the Metal Box that sits under the Monitor. This time  will try to get some in Kerstan Diimig of the interface Between the user and the Box the Monitor itself. My personal Choice was difficult i started out looking at prices cheap and suddenly realized that the Monitor would be what i stare at for hours on  that reason i purchased a Monitor that Cost along with the interface nearly As much As the computer. We discussed the different display standards last month and How they differ. So just what difference does the Monitor make several terms need to be defined to understand some of the Quality differences amount monitors. The picture Resolution usually refers to the number of individual dots pixels or picture elements that Are used to create an image. Resolution was discussed last month when describing the different standards for video interfaces. The higher the number of dots the sharper the image. Sometime Resolution is described As horizon Tal lines that make up the image. Again same principle the higher the number of lines the clearer and sharper the picture. Video Bandwidth is another of those foreign words used to describe the ability of a Monitor to put an image on the screen. The higher the frequency the More detail in the image. A color television will have a video Bandwidth of about 3 to 4 Mhz Megahertz White a Bandwidth of 30 Mhz and higher is common for very High Resolution graphics work scanning frequencies also affect the clarity of the image. A via Monitor would have a horizontal scanning frequency of about 30-38 Khz Kilohertz with systems that Are used for professional graphics presentation going up to about 80 Khz. The rather Mucky Cha display Monitor has a frequency of about i 5,75 Khz. The vertical scanning frequency is the rate at that the screen is redrawn. This frequency is normally Between 50 and 90 Khz or cycles. If the rate is too slow the screen will Flicker and Glimmer. Convergence is the ability of a color Monitor to converge at the same Point on the screen. Not exactly the same Point but a very tight group of the three colors red Green Blue that make up the picture f the Points touch or run into each other the colors will be Mushy or if too far apart the colors will look separated. Sometimes convergence can be corrected by adjustment but a poorly designed or Quillmon Tor cannot he corrected. Edge to Edge Sharpness is the ability of the Monitor to produce a Clear image from one Edge of the screen to the other and not just in the Middle. Dot pitch is a big Selling Point for Many manufacturers. Dot pitch is the distance in nil limiters Between the centers of two dots. In color monitors Dot pitch is the distance Between two dots of the same color. The Dot Pilch of an average color television is about 0.9 1 my while a Good Monitor will have a Dot Pilch of 0.31 my or less. The screen is coated on the inside will a phosphor coating. This Coaling is lighted up by the Light beam striking it. Only a personal viewing of the Monitor can determine if the phosphor persistence retention of Light is sufficient. Too Little will cause the image to Flicker and Loo much will cause the images to fade in and out instead of flashing offend on crisply this seems to be particularly prominent in. Green and Amer screens. Tinted non Glare coatings on the1 screen also Are something to be considered. There is nothing As tiring and irritating As a Light reflect my off the screen As you Are trying to work. # the company spotlighted this month is the John k. Kealy go. It s one of the oldest Exchange system vendors and distr buies a variety of products. They Are the Commodore representative and also handle the i Idaia line of printers and other products. The Kealy go. Holds seminars for Aal is repair personnel at regular intervals to insure thai after warranty repairs will be carried out Well. Each Exchange computer department should display a notice of when the Commodore Kealy representative will be available i hey have a Large stall throughout Europe a a big Aai Eshi tech Sale comes up aug. 30 through sept. 3. Keep an Eye Otil for the advertisement. Next month  will plunge ahead into the wonderful world of printers. Jerry kill ruler Rel comp Lur  a to Quot a Sauri end Carl Kramer i what Ever happened to Nimlo 3-d processing i Haven to used my camera in Over live years but i recall a Connecticut address following a move from Atlanta. There was even a european address mentioned to me. Processing was expensive As i recall about a $20 for 12 exposures from a 24-Frame Roll but 1 found this kind of photography  / \ r i have been running Down leads for Over three weeks so far with no Luck. Gan someone out there help with this i what is tie Best Way to take pictures of a drawing or photograph i Hae an photography Olympus of 77af, which sets the Speed of Stop and distance. Am i better off using my Lens at 35 my or 70mm? should 1 he close to the picture or farther away a / \ i use a tripod zoom your Lens to 70 my and get close enough to your subject to fill the Frame. Q i years ago i took a number of regular 8mm movie reels. I cannot recall Quot the Asa number for that Kodak color film. I think it was 20, the Only Speed available in those Days. Could that be right a / \ could be. 1 spoke with a Kodak representative and he confirmed that the 8mm movie film followed along with the development of still picture film 1 he earliest Quot modern Kodachrome was Asa 25, but there was an earlier version that was slightly slower. I also checked with a longtime film editor who confirms that the Asa 20 has to be close. I an you Tell me if the mar venous 4x4 pm super slide is finished for Good or is it possible to still buy 127 slide him a / \ i i spoke with an expert at Kodak and he told me that the 127 super slide film is no longer made. You can get 127 in Kodak Gold 200 print film and then have your negatives convened onto 120 slide film. You la get the same size image which can then be trimmed and mounted and although the 120 film is slightly larger than the 1 2 7, the conversion can he made to the exact size desired. , a  l  r it it a  la in 1 str m Ufi w.,v.
