HP-65 Standard Pac differences? - John Garza - 09-02-2008

I've had a couple of 65's for a few years, but just recently noticed that the mag cards in the two Standard Pacs are different.

One has SD-01A "Personal Investment"

The other has SD-01B "Days Between Dates"

I had always thought the "A", "B", etc. suffixes were new versions related to bug fixes/enhancements/etc. But this appears to be a completely different program.

Does anyone know the story behind this? Did HP do this with other Pacs?
