old spreadsheet extension *.wk1

[moniekvandun@hotmail.com (moniek)]

Hello,
I have an old spreadsheet, from 1989 or 1988, i think it is made on a
apple, the file format is *.wk1
Does anyone have a conversion program? Or can anyone tell with wath
program it is made? Excel is not able to open such old formats, also
the newest quatro pro can't handle the format.
I can sent the file to try to open if you think you can upgrade the
file to a standard format.

When you have a old mac, it will probably be able to open it and save
it, the macro's and calculations should be saved, i already have the
values, but not the formulas......

Thank you.

Greetings Moniek
