Last version of Excel that can read Excel v1 and Multiplan

[Elliott Roper]

From googling the group it would look like version 3 for V1 Excel for
Mac. Anybody hazard a guess for Multiplan?

I found some very interesting floppies from 1987 and 1988, and I'm
dying to restore the spreadsheets on 'em.

I need to dig an ancient Mac out of the attic, I'm trying to remember
when those ancient versions were current and which Mac I should brush
the cobwebs off first.
thanks
