It's the Code-1 address correction package; ~200k lines of code. Compiles and executes without a hitch, although we do have an SCO box in the corner, just in case we need tech support from the vendor. You may want to get the 2-user demo version of SCO, and install the software on that machine, then copy the installed software over to the FreeBSD box. I had to copy over /usr/lib/lang/, usr/lib/terminfo/, and some of the /dev/ directory as well. (Put the files in /compat/ibcs2, so they don't confuse regular FreeBSD programs). Performance-wise, you're going from 66mhz to 200mhz. Expect around a 3-6x speed increase, depending on the processor type you started out with ('030/'040/'060), and your workload (CPU or I/O bound). -Dan Nelson dnelson@emsphone.com
