Leonard L Krause founded Electronic Data Technology to market paper based tape word processing equipment to generate Reader’s Digest like personalized form letters. EDT also sells the first calculator with a single button square root key. It had 26 circuit boards! Word Processing products evolved to cassette tape, diskette, and eventually hard-drive based computer systems.


Leonard L and his son Len Krause founded Computer/Dynamics to market Basic Four computer systems. The Basic Four was one of the first multi-user mini-computer refrigerator-sized systems that used CRT displays and not punched cards for input. Computer/Dynamics begins to develop software for the Basic Four called Dynamo.


Computer/Dynamics enables Dynamo to run on a Personal Computer with an 80286 Intel processor and the SCO Xenix operating system, enabling for the first time, multiple users to run Dynamo on hardware other than Basic Four.


Computer/Dynamics becomes an authorized IBM Risc System 6000 reseller, making Dynamo available to companies with 30 to 300 users.


Computer/Dynamics releases its first Accounts Payable and General Ledger modules eliminating the need for third party packages.


After the completion of all Y2K projects, Computer/Dynamics releases DynaWeb, which provides real-time online access to Dynamo data for your customers.

Computer/Dynamics makes the transition from AIX and SCO Unix operating systems to Red Hat Linux, and recommends that platform to all customers, even those with a large number of users, previously limited to AIX based systems.

Computer/Dynamics releases a version of Dynamo Tools and Dynamo based on the new BBj language offering enhanced functionality.
