[1] The American company's first major product, the Otrona Attaché, came out in April 1982 and folded up to the size of a fat briefcase painted off-white with orange trim.

It contained a single speaker for sound output (which could be set to give audible feedback when keys were pressed)[9] and two RS-422 serial ports for communication.

[10] It also supported monochrome bit-mapped graphics, and introduced the concept of desk accessory programs, such as a calendar, calculator and auto-run timer that could be run without closing a user application.

The brainchild of Ron Lingeman, a gifted H-P alumnus, the Attache was significantly smaller, sleeker, lighter and faster than the Osborne 1 and other portable computers of the time.

Otrona engaged in a ground up development effort of the more, but not yet fully, PC-compatible 2001 computer, incorporating a PC BIOS written by Steve Gray.

Despite the innovative packaging, added features and superior performance, this $3,995 product ended up costing more than anticipated to produce, and never had a chance to succeed as it pushed further the failure of Otrona that filed for bankruptcy shortly after its release.
