Recently bought an old Power Mac 7500/100. Running System 8.1. When I try to install games with multiple floppies..when it says to instert disk 2, I do so. Then the disk is ejected and I am asked to insert disk 1 again, I do so. Then the whole system locks up and I have to force the install to stop. Anyone know why this is happening and how i can fix it? This has happened with 3 different programs. Thanks in advance.
