[comp.sys.zenith] How to make a Z-200 act like an XT?

birnbaum@paul.rutgers.edu (Rich Birnbaum) (01/15/91)

I want to slow my Z-200 down to XT speed so my games don't whiz by so fast.
I know you go into ctrl-alt-ins mode and do an 'o' command but I forgot the
parameters to 'o'utput to port.  Can someone help me?
