Thanks to +Debra Dalgleish for alerting me to the date tomorrow - September 30. On that day in 1985, Excel (for the Mac) was released. That's 30 years ago. I hunted around for some old Excel and found Excel 2 for Windows (the first version for Windows). It comes with its own Windows runtime environment since Windows at that time was not commonplace. I managed to make it survive long enough to type in =NOW() - it's running in Oracle Virtualbox and the platform might not be 100% emulating well.
