T100-X Dynapad

Long before the tablet PC craze of fall 2002, there was the Toshiba T100X Dynapad. The T100X was a "pen-based computer" (This was before the term "tablet PC" existed) which ran on a 25MHz 386 AMD CPU. It shipped with 4MB RAM and had a 40MB hard disk drive for storage. It did not include an internal floppy disk drive, but a separate external floppy disk drive could be purchased.

Similar to most modern tablet PCs, the T100X did not have a built-in keyboard, and mouse pointing was done with a stylus. However it did contain ports to connect an external keyboard and serial mouse. It also contained two Type II PCMCIA slots, but it has been said configuring PCMCIA devices to work properly was often difficult. A parallel port adaptor was also included.

The display consisted of a backlit 9.5" grayscale touch-sensitive LCD with a standard VGA resolution of 640x480 pixels at a color depth of 16 shades of gray.

The T100X was often shipped with Windows 3.1, along with specialized drivers (Microsoft Pen Services for Windows 3.x) to enable pen and handwriting support in applications, and to allow the stylus to function as the mouse.

The T100X weighed approximately 3.3 pounds, amazingly lightweight for portable PCs of the time (This was back when notebook computers easily weighed at least 8 pounds).

Thanks to Torin Darkflight for info and pictures.


I can''t believe I trashed my working T100 pad in the dumpster about 20 years ago. Battery didn''t hold charge long though. I use to run a GeoCities page dedicated to the T-100X.

I owned one of these in the late 90s, and loved it. The screen was not touch, but rather was responsive to the pen via weak RF signals. The pen also needed a battery, which ran down rather easily. (AAAA as I recall). I updated mine to run Win3.11, which included easier PCMCIA services. The writing app was really outstanding as well. It recorded the pen strokes as vectors, not as raster. The allowed it to do post-writing OCR as well as real time (which was slow and could be turned off). Was quite sad when mine finally died a few years ago.

I was in Japan at a Product Planning meeting when we were trying to name the new box. We didn''t want to confuse it with the T-Series line of "laptops" (i.e., T1200, T1600, T3200, etc.). We decided to use only 3 digits, but that didn''t seem obvious enough of a distinction, so I suggested we put the "X" on the end, to signify "handwriting".

I told the Japanese guys that, in the old days when some people couldn''t write, they would "sign with an X" (also the reason you still see an "X" at the beginning of the signature line on forms). Of course, in Japan they''ve never "signed" things longhand, so they had no idea what I was talking about. But nobody had a better idea, and they trusted me that it would "work" in the West, so it stuck: T100-X.
