Abstract: System selection was made in 1977. CLSI, DataPhase, and Systems Control were the three systems considered. DataPhase was deemed to be the least cost over a 7-year period. DataPhase based on a version of MUMPS. DataPhase used a standard programming language and ran on unmodified computer hardware. (CLSI made mofifications to hardware.) DataPhase hardware included a Data General Eclipse S/130 processor with 2 disk drives. Two additional drives were added by 1980. 896KB memory. 48 1200 baud modems. Software uses the ALIS database. The library system insisted on a MARC bibliographic database. DataPhase was the only turnkey vendor that offered this capability in 1977. By 1890 the system had expanded to the maximum of 4 drives, which was the maximum that the hardware of their current system would support. The database had grown faster than expected and the system was at full capacity. It was recommended that the system be upgraded to the DataPhase ALIS II/E system that ran on Tandem computers. This would also alleviate problems in slow response time.
