Timetable. SESA equipment is scheduled to be installed during fiscal years 1989 and 1990. Regional offices will inform SESAs when the machines are scheduled for installation as well as provide site preparation instructions. Commercial software is not anticipated to be ready for distribution until the fall; however, Artecon will begin delivery of machines earlier in order to meet phased delivery schedule commitments. As a result, some SESAs will receive equipment before software is available.
