In src/sattrack.h, set SATDIR to /local/lib
and changed printer parameters to:
#define PRINTCMD              "lp"
#define PRINTOPT              "-dstar"
#define FONT                  "-o"
#define SIZE9                 "pic"
#define SIZE10                "pic"
#define SIZE12                "eli"

In Makefile, set
# SCO 5.0        (SCO Open Server 5.0 using stock devsys)
#
CPU             = i386/SCO
CC_CMACH        = -belf -O -DSVR4
CC_LMACH        =
CC              = cc

CC_CUSR         = -DREVERSEVIDEO -DSUNTRANSITS -DXWINDOW #-DHOMEDIR

Removed test for "true xterm" in sattrack/sattrack.c

In data/defaults0.dat, set:

setenv USER public (cron does not set USER)
