Excel 2010: Where It Came From
1 Excel 2010: Where It Came From In This Chapter ● Exploring the history of spreadsheets ● Discussing Excel’s evolution ● Analyzing why Excel is a good tool for developers A Brief History of Spreadsheets Most people tend to take spreadsheet software for granted. In fact, it may be hard to fathom, but there really was a time when electronic spreadsheets weren’t available. Back then, people relied instead on clumsy mainframes or calculators and spent hours doing what now takes minutes. It all started with VisiCalc The world’s first electronic spreadsheet, VisiCalc, was conjured up by Dan Bricklin and Bob Frankston back in 1978, when personal computers were pretty much unheard of in the office environment. VisiCalc was written for the Apple II computer, which was an interesting little machine that is something of a toy by today’s standards. (But in its day, the Apple II kept me mesmerized for days at aCOPYRIGHTED time.) VisiCalc essentially laid theMATERIAL foundation for future spreadsheets, and you can still find its row-and-column-based layout and formula syntax in modern spread- sheet products. VisiCalc caught on quickly, and many forward-looking companies purchased the Apple II for the sole purpose of developing their budgets with VisiCalc. Consequently, VisiCalc is often credited for much of the Apple II’s initial success. In the meantime, another class of personal computers was evolving; these PCs ran the CP/M operating system. A company called Sorcim developed SuperCalc, which was a spreadsheet that also attracted a legion of followers. 11 005_475355-ch01.indd5_475355-ch01.indd 1111 33/31/10/31/10 77:30:30 PMPM 12 Part I: Some Essential Background When the IBM PC arrived on the scene in 1981, legitimizing personal computers, VisiCorp wasted no time porting VisiCalc to this new hardware environment, and Sorcim soon followed with a PC version of SuperCalc. -

About half of the collection consists of software in floppy disk and cassette formats. Most of this portion of the collection pertains to CP/M and applications that were written for the CP/M operating system. The other half of the collection contains text documentation such as reference manuals and user guides for a variety of software and hardware. A significant portion of the text is related to hardware, some of which was donated with this collection and is cataloged separately. Notable companies in this collection include Advanced Computer Design, Advanced Digital Corporation, Epson, Hewlett-Packard, IBM, MicroPro, and Tektronix. -
