At this site, in the left column, there is a information about PSR-740.
It's necessary to have installed the Real Player to see
and hear a small demonstration.
When I see (using the Real Player) the demonstration
the PSR 740 has a different design at Mike input and also
some messages that appear in the display are different
of my 740.
Can others 740 users confirm this?
Is there a new EPROM release?
