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.

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.
