I picked up this MZ-700 application. I enjoy poking around with them, just to see what productivity was really like back then. The most productivity I can recall doing back in my childhood was using Magic Desk I on the Commodore 128. It was basically a typewriter emulator, so doing more sophisticated things like this spreadsheet application is a pretty new experience for me.
It loaded (on the fourth time) and I was up and running. I could figure out some of the basics, such as entering text, entering numbers, inserting and deleting rows and columns, adjusting column width, and entering the expression editor to perform simple mathematical calculations. The one thing I really would like to figure out but couldn’t is how to perform calculations by cell reference (for example, in Excel, navigating to C1 and entering “=A1+B1” would add the values of A1 and B1 and put it in cell C1). I can’t seem to find any syntax for it online, and in fact, I can’t seem to find much about this program at all! So it’s more a curiosity.
