Grand Father 'Spread Sheets'

If I say "Spread Sheet", immediately you'll lock on to MS-Excel. The word SpreadSheet itself is mostly unknown to the new generation.
Some of you may remember our grand old "Lotus 1-2-3", the Spread Sheet package (under MS-DOS) during the 1980s. LOTUS 1-2-3 was the king of all PC applications ( I won't forget the WordStar and DBase, siblings of Lotus 123) ! But some of you may remember the "VisiCalc", the pioneer in SpreadSheet packages. But how many of you are aware that SpreadSheet packages existed even before VisiCalc ? You may, if you were familiar with Home Computers, and the MSX versions of them.
I've below, the snaps of a SpreadSheet package ( as a ROM crtridge), for use with MSX version Home Computers (Not the Sinclair Spectrum s ! ).
