This early tablet has the AT&T Hobbit RISC-based processor running at 20 MHz, 4 MByte of RAM and a 10Mb storage card. The touch screen is a high contrast, 110 dpi reflective LCD, 640 x 480 pixel resolution, screen size 5.9″ x 4.3″. 

EO Computer Ltd manufactured an early commercial tablet computer created by GO/Eo (both later acquired by AT&T) and released in April 1993. Eo (Latin for "GO")was the hardware spin-out of GO. It was similar to a large personal digital assistant with wireless communications and competed against the Apple Newton.
 
The unit was later produced in conjunction with the Frog design, Matsushita, Olivetti and Marubeni corporations.

Between 1991 and 1993 EO Computer Ltd was based in the old Torch Computers building in Great Shelford near Cambridge in the UK. Dr. Herman Hauser was Co-Chairman of the company.
