The UCLA MEDLARS computer system.
Under a subcontract with UCLA the Planning Research Corporation has changed the MEDLARS system to make it possible to use the IBM 7094/7040 direct-couple computer instead of the Honeywell 800 for demand searches. The major tasks were the rewriting of the programs in COBOL and copying of the stored information on the narrower tapes that IBM computers require. (In the future NLM will copy the tapes for IBM computer users.) The differences in the software required by the two computers are noted. Major and costly revisions would be needed to adapt the large MEDLARS system to the smaller IBM 1401 and 1410 computers. In general, MEDLARS is transferrable to other computers of the IBM 7000 class, the new IBM 360, and those of like size, such as the CDC 1604 or UNIVAC 1108, although additional changes are necessary. Potential future improvements are suggested.
