Flash MX / Flash 5 Mac readability

This takes a little background to ask the question…

I work for this guy who loves Mac computers as he is in advertising.
He does not understand the fact that Writing websites do not require huge files, so PC computers are way better for creating websites than Mac computers.

He bought this G4 for me to write websites on thinking it is sooooo wonderful. He tried to do a good thing. But Macs are not good at all for writing websites, at least not OS 9 and he will not let me use os 10 because he does not know how to use it.

I am a web designer for that company and since he only knows how to use OS 9, he will not let me use OS 10.

I have been writing websites using flash mx and he cannot see them as he is using 4 point someting Netscape.

He says I have to write the websites so HE CAN SEE THEM on his outdated mac running outdated browser software.

I wanted to use flash to write sites, any suggestions.
I can not even get a stupid flash dynamic scroller to show up for him.
