I finally completed installing and configuring GEMPAK and McIDAS on Solaris 8 x86 and it is working fine. The only thing I haven't done yet is the run the decoders (I am still using Solaris 7 on another drive for that), but I have mounted by data disk under Solaris 8 and have exercised the two thoroughly and haven't found any problems (not that there really should be).
