I AM a Form Seven student who operates a bulletin board service (BBS). I want to open a multi-line on-line system and am interested in a multiport card called DigiBoard/PC8i. This board includes eight com-ports as well as eight 80186 microprocessors (the latest version includes 80960 microprocessors). If I opened windows in DESQview/X 1.02 for eight lines on a 33-megahertz IBM PC 486DX with eight MB of RAM, will the speed be affected? If so, how can I increase my CPU's speed? TIGER LIE Hunghom DESQview is a memory-hungry terminal emulation program, and on a PC with only eight MB of RAM - even a 33-MHz 486DX - it will run painfully slowly. You could increase overall speed by installing at least 16 MB of RAM, and you might consider upgrading your system to a 66-MHz DX2 microprocessor. I WANT to attach a joystick to my portable computer. I have a mouse connected to the nine-pin serial port. Maybe I should lie and tell you I want the joystick for a business graphics program, but I really want it for the flight simulator program I enjoy on my desktop computer. MICHAEL WONG Discovery Bay Colorado Spectrum in the US understands your frustration because it makes a device called the Notebook Gameport which sells fo US$49.95. It allows you to attach almost any joystick or other game device directly to your IBM-compatible portable computer. The gameport, a four-axis device, allows you to attach two joysticks or a joystick and rudder pedals simultaneously. The Notebook Gameport attaches to your notebook's nine-pin serial port, but its pass-through serial mouse port gives that nine-pin connection back to your mouse. Notebook Gameport is not available in Hong Kong. To order, you have to call Colorado Spectrum in the US on (303) 225-6929. I HAVE always wondered why computers are classified into desktops, laptops, notebooks and palmtops. Can you clear this up for me? JOHN PROCTOR Mid-Levels Desktops, obviously, are the machines that sit on your desk because they are too large to carry around or fit on people's laps without breaking bones. If a portable weighs more than about 2.5 kilograms and measures about five centimetres thick, it is considered a laptop. If it is about 2.5 cms thick and weighs about 1.25 kg, it is referred to as a notebook model. And if it can rest in the palm of your hand and weighs 500 grams, you have a palmtop computer. To make classifications easier, or even more confusing, depending how you look at it, American Business Concepts has come up with a desktop solution for laptop computers called the Laptop Desk. This device is designed specifically for laptop computers and sports a tiltable reading-table surface that easily accommodates almost any portable computer. The movable surface puts the laptop in an ergonomically correct position for reading and typing. To the right sits an adjustable page-holder with a flexible-neck halogen lamp. Below the copy holder is a utility tray for pens, pencils and paper clips. Below the tray are three organiser shelves for books and papers. Underneath the shelves sits a printer stand. Room to hide transformers, powerstrips and other bulky devices is available under the printer shelf. A single hollow leg hides those ugly printer and power cables - and adjusts the desk to heights ranging from about 60 to 75 cms. The entire desk, reversible for right-or left-handed usage, is easily moved on the three casters attached to the Y-shaped base, which is similar to those found on bedside hospital tables. In fact, you can use the Laptop Desk in bed for that very reason. Enter the bedtop.
