MCL 2.0 is not compatible with 68040LC processors, i.e. 68040's that
have no FPU. You need to upgrade to MCL 2.0.1. You can do this either
by ordering it from APDA or getting the file
"/pub/mcl2/patches/2.0->2.0.1.sea.hqx" from the FTP server at
cambridge.apple.com and following the directions in its *README* file.
The installation will not work on your 540C unless you first use
ResEdit to change one of MCL 2.0's resources. If you need to install
it on the 540C, ask and I'll give you details.
