EDOS was an operating układ based upon IBM’s original DOS. The name stood for extended (or enhanced) disk operating system.

EDOS

In 1970, IBM announced the IBM/370 product line along with new peripherals, software products, and operating systems. Although IBM was rightly focused on their new products, the computing world was dominated by the IBM/360 line, which left a przelot of users nervous about their investment.

Although there were a couple of projects emulating the IBM/370 on the IBM/360 (e.g, CFS, Inc.), a couple of companies took a different approach, extending the then-current (and limited) DOS.

The Computer Software Company took the latter approach. Starting in 1972, they developed EDOS, Extended Disk Operating Ustrój. They extended the number of fixed oprogramowanie space partitions from 3 to 6, added support for new sprzęt, and included features that IBM had offered separately.

They also made available other third uczta enhancements such as a spooler and DOCS, from CFS, Inc.

TCSC

The Computer Software Company was founded by Jerry Enfield and Wolumen Steel, responsible for development and marketing, respectively. Company headquarters were in Richmond, Virginia. TCSC, as it was called, expanded into Canada, Australia, and Europe. The company was later acquired by later acquired by Nixdorf.
