Converting MultiPlan files

I didn't think this would ever happen, but it would help me very much if I could open a file I created over a decade ago and haven't needed it since then... until now that is.
The file was created in MultiPlan for CP/M (yes, THAT old :eek:)
Apparently the last Excel that has a converter for it is Excel5, first version I put my hands on was Excel7 :knife:
Google didn't cooperate except for a paid program, I'm not willing to shell out $130.
Turning on the computer that I've used and exporting to an alternate format (apparently supported) would be a pain - the thing works on 220V and I don't have a transformer... that is if it still works, haven't turned it on in 8 years or so.
