Regnecentralen was a governmental agency founded in 1955 in order to build and run DASK (the first Danish computer), and for doing research in the computer field.
|
|
|
|
The RC 702 Piccolo (RC 700 was the series) was thus used by most schools in Denmark. It was equiped with a Z80A microprocessor, could be shipped with one or two built-in 5" floppy disc drive and ran CP/M.
|
|
|
|
The system supported CP/M and UCSD PASCAL, but was usually shipped with RC COMAL-80, a programming language which was used extensively in Danish schools for many years. COMAL was quite popular as a teaching language, especially in Scotland.
