Otrona Attache

The Otrona Attache was a compact Z80-based CP/M portable computer produced from 1982 to 1984 by Otrona Advanced Systems Corporation of Boulder, Colorado. It was much smaller and lighter than its contemporary competitors made by Osborne and Kaypro. It also had better graphics capability and used 360k diskettes which held four times more than the Osborne I's. These benefits meant that it was accordingly more expensive and didn't sell very well. Fewer than 10,000 were built over those 3 years, including the Otrona Attache 8:16 which had an 8086 processor and was MS-DOS compatible. Otrona unfortunately went out of business before they could sell very many of the Attache's 8088-based successor, the Otrona 2001.

This webpage is still under construction, and since Otrona Attaches are cool little guys, I do hope to add more to it in the near future. (How many times have you heard that?)

The Otrona Attache came with one 360k diskette with CP/M, MBASIC-80, WordStar, Charton, and various Attache-specific utilities. In addition to this, I have a box of diskettes with programming languages, games, and other software. Since this is a fairly rare machine which uses its own disk format, you won't be able to do much with your Attache if its diskettes are missing. I can send you a spreadsheet listing the contents of the disks I have and can make copies for you for a modest fee to cover my costs. Contact me at schreibstang /at/ gmail /dot/ com.
