PC Plus was released in 1985 with the primary goal of ease of use. An early employee said its functional design was inspired by the combination of a manual ledger journal, an Epson FX 80 printer, and a Canon calculator. Incidentally, Peter Bang is the grandson of one of the founders of Bang & Olufsen, the manufacturer of home entertainment systems par excellence.
PC Plus was a PC DOS-based, single-user system. PC Plus' design included the following features:
- An interface resembling the use of documents and calculators
- Online help
- Good exception handling
- Minimal reliance on computer resources
The PC Plus product was marketed through dealers in Denmark and Norway.
