* History of Didact
*------------------
* Didact Läromedelsproduktion was started in Linköping in Sweden by Anders Andersson, Arne Kullbjer and
* Lars Björklund. They constructed a series of microcomputers for educational purposes such as "Mikrodator 6802",
* Esselte 100 and the Candela computer for the swedish schools to educate the students in assembly programming
* and BASIC for electro mechanical applications such as stepper motors, simple process control, buttons
* and LED:s. Didact designs were marketed by Esselte Studium to the swedish schools. The Candela computer
* was designed to be the big breakthough and was based on OS9 but lost the battle of the swedish schools to
* the Compis computer by TeleNova which was based on CP/M initially but later both lost to IBM PC.
*
* Misc links about the boards supported by this driver.
