Otrona Advanced Systems (Boulder, Colo.)

Some considered the Otrona superior to the Osborne, as it was well made but smaller. The single-floppy drive model was called the Attache S. The Attache 8:16 used the same case as the Attache, but had updated electronics to accommodate a second 16-bit CPU. A Tempest version of the Attache 8:16 was introduced in 1984.

The Otrona 2001 could be configured as either a portable or a desktop PC. As a portable, its built-in CRT could tilt up for better viewing. As a desktop, a panel covered the slot for the built-in display and a standalone monitor was used.
