Conversion from RSX-11D to RSX-11M or: Did I Really Want to Do It

摘要

The LAMPF Nuclear Chemistry Data Acquisition System (DAS) is used to acquire and to process data from a variety of nuclear chemistry experiments. In June 1977, the DAS was upgraded to a PDP-11/34 and RSX-11D V6.2 and FORTRAN 4-PLUS V2.5. That software remained in use until January, 1984 even though the PDP-11/34 was replaced by a PDP-11/44, and a number of peripherals were added or replaced. The arrival and installation of an RA-60 disk system forced us to upgrade to RSX-11M V4.1 and FORTRAN-77 V5.0. This was not without much pain and many problems. There was a change in functionality, and some things did not work as they previously had worked. A description of some of the changes in the DAS and of the problems in going from the ancient to the current software will be given as well as an evaluation of the results obtained so far in the conversion.
