Hallo

PC/GEOS und vorallem PEN/GEOS sind von Haus aus Touchscreenfähig. Die nötigen Treiber sind dabei.
Bei Fragen schreibt ihr einfach an Frank S. Fischer. Breadbox hat z.b. Ensemble erfolgreich mit diversen Kiosksystemen, Touchscreens getestet, wie mir FSF bereits vor Jahren per Email schrieb.

Tschau

a) Es gibt keine "Stifttreiber", sondern nur Treiber für den Touchscreen.

Zitat

b) Die Touchscreen-Treiber von Zoomer, Omnigo, Bullet, ... laufen nur auf diesen Geräten, da sich wohl kein anderes Gerät mit genau denselben Chips und derselben Touchscreen-Auflösung finden wird.

Zitat

c) Jeder "normale" Touchscreen ist als Maus oder als Grafiktablett ansprechbar. Ggf. funktioniert er schon mit den Treibern, die Geos beiliegen. Ggf. muß aber auch erst ein DOS-"Maus"-Treiber geladen werden, damit dann unter Geos der "Generic Mouse"/"Generic Tablet"-Treiber funktioniert.

Zitat

d) Ob ein Touchscreen "normal" ist oder nicht, hängt nicht davon ab, welcher Stift / Finger damit funktioniert, sondern ob der Hersteller sich an irgendwelche Standards gehalten hat oder ob er wenigstens Dos-"Maus"-Treiber beigelegt hat. Toshiba war leider dafür bekannt, bei seinen Laptops & Co. Standards und DOS-Treiber zu ignorieren, siehe auch die Bemerkungen zum T100X. (Selbst mit Win3.x hatte man damals so einige Probleme, da nur genau die Versionen liefen, die mit dem Toshiba-Gerät ausgeliefert wurden.)

The Toshiba Dynapad "Pen Computer" was announced in November of 1992. It weighed 3.3 pounds, contained a 25 MHz AMD processor 386SXLV (low voltage), and had a built-in 40 Mb hard drive. The battery life was about 2 - 3 hours. Software was either Microsoft's Windows for Pen Computing or GO Corporation's PenPoint. It measured 10.6 inches long by 8.3 inches wide, by 1.6 inches deep. The suggested retail price was $3,499 (January 1993).

The Toshiba T100X is reported to work with NewDeal software. It may take some work to find a mouse driver for the T100X pen.

First Impressions
[SIZE=3]Two Toshiba Systems to Go [/SIZE]

[SIZE=2]Toshiba stays on the cutting edge with a 3.3-V 486 notebook and a promising pen-based system [/SIZE]
Gene Smarte

Toshiba America Information Systems thinks that a lot of business users are in the market for a more powerful notebook. It also believes that a smaller group of computer users with specific applications needs a pen-based system. Based on a look at preproduction versions of the T4500 series notebooks and the Dynapad T100X, Toshiba should have hits in both categories.

T4500: Beefed Up for Business

According to Ron Smith, product marketing manager for Toshiba, the T4500 is targeted at business users. Considering what's included in the system, though, power users won't be disappointed, especially with the competitive pricing. Suggested retail prices are $2799 for the system with a monochrome display and $4399 for the system with an active-matrix color display.

While you'll pay a hefty price for the T4500C with its color display, its 615-pound weight compares favorably to the monochrome version's 6 pounds, and its thickness increases only slightly from the 1134 by 813 by 145 inches occupied by the monochrome version. The monochrome display is 912 inches diagonally, with 640- by 480-pixel resolution and 64 shades of gray. The color display is also 640 by 480 pixels, but it has 256 simultaneous colors. It measures 825 inches diagonally.

Aside from the major display and minor weight and thickness differences, the two units are identical. Both use a new 3.3-volt 20-MHz Intel 486SX processor. Keith Comer, senior product planner, said that Intel asked Toshiba if it wanted a 3.3-V 486SX. This processor fit in with Toshiba's future plans, and the company designed the T4500 with the new processor in mind, including use of 3.3-V RAM.

Smith says that while Toshiba believes it's the only company using the processor right now, Intel may make it available to others. The 486SX includes 8 KB of internal cache memory. According to Toshiba, the T4500's battery life will equal or surpass systems based on Intel's new 3.3-V 486SL (see the text box "A Higher End for Compaq Notebooks" on page 47).

The T4500 includes a nifty LCD strip that replaces the usual set of LED status indicators. Icons show battery capacity remaining; power-saving modes; hard disk access; cursor, number, and Caps Lock modes; and other system operating conditions. This is a nice, well-executed touch.

Other standard system features are an 80- or 120-MB hard drive, 4 MB of RAM (user-expandable to 20 MB using Toshiba's memory cards), a 1.44-MB floppy drive, an 18-mm PCMCIA slot, and a snap-on (i.e., no-cord) Microsoft Ballpoint pointing device that clicks into a hot-shoe connector on the right side of the system. Smith acknowledges that this puts left-handed users at a disadvantage, but Toshiba will exchange the Ballpoint for a traditional mouse.

Around back are connectors for simultaneous external video output (up to 1024 by 768 pixels), serial and parallel expansion, Toshiba's docking station, and an external keyboard and mouse. There is no coprocessor socket. A PCMCIA modem card that fits entirely inside the machine, including the jacks, is in the works.

The monochrome system comes standard with a nickel-cadmium battery pack that will give you more than 3 hours of typical use. The color system includes nickel-metal-hydride batteries that also provide at least 3 hours of life.

Smith says that you can expect about 20 percent and 38 percent speed improvements, respectively, in Excel and Word compared with a 25-MHz 386SL. Going to 3.3 V also gets you about 40 minutes more operating time per charge. While I didn't have time to fully discharge the battery pack, the BYTE benchmarks showed that the T4500's performance ranks it about where you'd expect: between a 33-MHz 386 and a 25-MHz 486 desktop system.

Dynapad T100X: Pen Progress

Toshiba admits that pen-based computing is a vertical market. The technology, particularly the handwriting-recognition capability, just isn't ready for broad-based applications. There is, however, plenty of pen appeal for niche applications.

The Dynapad is built around a 3.3-V 25-MHz 386SLV from AMD. This sleek electronic tablet measures 1025 by 7110 by 125 inches and weighs just over 3 pounds. Kyp Walls, the senior brand manager for Toshiba, says research suggests that 3 pounds is the most a user wants to lug around all day.

The Dynapad has a 40-MB hard drive (with 18-millisecond access), 4 MB of RAM (user-expandable to 20 MB), a 9 1/2-inch VGA (i.e., 16 gray scales) transreflective display, two PCMCIA slots, and serial, parallel, PS/2 keyboard, and floppy drive connectors. Power comes via nickel-metal-hydride batteries, with a nominal operating time of 2 1/2 hours. Walls said that the batteries may last up to 7 hours if the system remains in the lowest power-comsumption mode. Recharge time is 1 1/2 hours.

You can order the Dynapad configured with either Windows for Pen Computing or PenPoint. The pen fits into a slot on one end of the enclosure and remains visible. Toshiba reports that while some pen-based systems store their pens out of view, this can lead to trouble if you don't notice that the pen isn't in its storage compartment.

Walls says that many projected Dynapad owners will use the system outdoors. The backlit transreflective screen lets you turn on backlighting when needed. In sunlight, however, you can switch off the backlighting and still have a readable display. At night, you can use the backlight; during the day, save the batteries and let the sun do some of the work.

While handling the Dynapad, I had some reservations about being able to hang on to the smooth, rounded-corner design. The rubberized-paint finish does provide a finish that can be gripped, though, and different cases (some water-resistant) should be available soon.

It's difficult to get too excited about pen-based systems unless you have a specific use in mind. Toshiba believes that medical personnel, salespeople, fleet workers, and nonoffice workers everywhere are eager to move from paper to pen. Meanwhile, the promise of pen-based computing continues to intrigue us all, and the Dyna-pad is a great example of technology in progress.
