Replying to Jibberish

OK so i have a G5 mac and it's impossible to play jibberish with anything i tried virtual pc and Q emulator

so i was wondering if there was a way to use my mac as my old win 98 screen so i can save some room because i don't use it for anything other than jibberish and taking away the giant monitor would be great

i also looked at the thread about dual monitors and i might get a new monitor that i could switch between the two

or do i have any other options so i can save space
