I've still got a few hundred cards, but I didn't realize an II+ would swallow them!
Ahh... Visicalc --- there's a good program.
You wouldn't believe the data analysis I did with that baby. It probably required about three times as many 'phantom' columns for the intermediate calculations as today's spreadsheets would require, but I did some good work on that. Really, though, most of my work today would be just fine with it. The graphics display would be a bit tough to massage into now, though.

Mindblowing trivia: The PC version of VisiCalc is only 27.5K. There are pictures on this very thread bigger than that.
BTW, you can download and run a legal copy of the original VisiCalc. It's only the the PC version though; the author couldn't get permission from whoever owns the Apple II version now, I guess.
