SuperCalc
SuperCalc was a spreadsheet originally developed by Sorcim and, continuing since the takeover in 1984, CA Technologies. It was very successful under the operating systems CP / M and DOS. The last version was released in 1993 for Windows 3.1.
In the GDR, a similar program was offered as "KP" ( spreadsheet ) from the Kombinat Robotron under the operating system SCP, a CP / M 2.2 derivative, on various 8-bit microcomputers.
