The Zorba is one of the last 8 bits portable computer running the CP/M operating system. Its features were almost identical to the [Kaypro II](/museum/kaypro-ii/).

The Zorba was first manufactured and sold by Telcon, a company specialized in telecomunication equipments manufacturing.

For $190 more, the user could order the **Perfect Software Package** including the 'Perfect Writer' word processor, the 'Perfect Speller' spell checker, the 'Perfect Filer' database manager and the 'Perfect Calc' spreadsheet.

Having spent a lot of money designing the Zorba, Telcon was seeking for new investors to market its portable and settle a network sales. It was then bought up by **ModComp** (Modular Computer), a company specialized in mini-computer manufacturing. A group called **Modular Micro Group**, specialized in Zorba marketing was created. In spite of that, results were very bad and one year after its launch date, Zorba computers stock was sold to a company specialized in selling off surplus stocks, wich sold them at a very low price.

Zorba users were nevertheless very satisfied. They were able to read practically every existing CP/M floppy format. Its several video emulations (H19/Z19/VT52) allowed them to run virtually any existing CP/M software.
