Irv,
I did purchase the Headstart at that time and still have the software that
was used to run the 1989 Grolier on it. I did notice that some of the
discs and programs that came with that computer were rigged so as to only
run on the Headstart. I went on to later editions of Grolier's and don't
actually remember trying this particular Headstart disc on other computers.
anyway, if you E-mail me your address I'll mail you a copy of the software.
