The Compaq Concerto was a laptop computer made by Compaq, introduced in 1993. [1] Concerto was the first tablet computer manufactured by Compaq on a large scale.
Specifications
There were three Concerto models, varying in hard disk capacity, and processor speed. All had 4 MB of RAM soldered to the motherboard, which was expandable to 20 MB using proprietary memory modules.
There were two processor options: Intel 486SL @ 25 MHz or 33 MHz. The 25-MHz model was available with either a 120-MB or 240-MB IDE hard disk drive, and the 33-MHz model had a 240-MB IDE hard disk drive. Both models had a built in 3.5" 1.44-MB floppy disk drive.
All models shipped with MS-DOS 6.2, with Compaq's unique set of DOS extensions for power management, configuration and model specific help. Windows for PEN Computing Version 1, which was Windows 3.1 with necessary add-ons for pen operation — including handwriting recognition - was also pre-installed.
- Modem: Internal modem was available as add-on
- PCMCIA: two Type II PCMCIA slots, could also be used as a single Type III PCMCIA slot
- Docking Station: a Concerto specific docking station was available
The Concerto was not a very successful laptop, but it did have some special features: a detachable keyboard, and a pen & touch screen (the touch screen only worked with the special pen). It could be considered to be ahead of its time.
Its screen had Wacom functionality:
- The pen had a button which could produce a double-click or right-click. (Touching the screen gave a single-click.)
- The position of the pen could be detected, and the correctly placed pointer could be displayed, even when the pen was up to 1 cm away from the screen. This could e.g. trigger tooltip text display in newer operating systems.
The Concerto was a unique design, in as much as it was "upside-down" - the main body including the motherboard, hard disk drive, floppy disk drive, and expansion slots were behind the screen. The detachable keyboard was used as the lid but could be completely removed, at which point the Concerto became what is known as a slate PC. The pen was connected to the Concerto through an RF link, and there was a compartment in the Concerto for the pen.
