Several exciting technical advances fostered the improved environment for computer use at pharmaceutical companies in the 1980s. The first was a development of the VAX 11/780 computer by Digital Equipment Corporation (DEC) in 1979. The machine was departmental size, that is, the price, dimen-... 

Until 1978, the realm of computational chemistry was limited to those who had sufficient access to mainframe computers. In 1978, however, the Digital Equipment Corporation (DEC) introduced the VAX 11/780 minicomputer. These computers were smaller, cheaper, and easier to use than the older mainframes, and these traits meant that more institutions than ever before could afford to own them, which in turn meant that more chemists than ever before had access to computational facilities. As Richard Counts, the director... 

Digital Equipment Corporation (DEC) introduced a sophisticated minicomputer, the VAX 11/780, in the mid- to late-1970s. At prices of 300 k USD (and up), machines could be acquired that were as fast as 1960s multi-million dollar mainframes. Double precision meant 64-bit words, and multiple external disk drives could be added to provide hundreds of MB of storage. DEC was not the only producer of minicomputers, and before long, with different vendors and models, their use for computational chemistry became fairly widespread. 

This system currently consists of ChemSketch (written in-house), REACCS and MACCS (from MDL)and DECpage and All-in-1 (from Digital Equipment Corporation, DEC). 

In the area of computer hardware and operating systems the chemical/pharmaceutical industry increased its use of Digital Equipment Corporation (DEC) VAX computers with the VMS operating system, increased its use of IBM PC computers, and began to talk about more exotic workstations and parallel processors. 

There are debates as to which computer was the first minicomputer, but many credit Digital Equipment Corporation (DEC), for many years the largest company in the minicomputer field, wifh fhe introduction of the first commercial minicomputer in 1959-1960, the PDP-1, a second-... 

In the 1970s and 80s, computers such as PDP-8, PDP-11, and VAX from the Digital Equipment Corporation (DEC), or other manufacturers such as Honeywell, became widespread in industry. These were generally known as minicomputers (to differentiate them from the older, larger mainframe computers) although they were still each the size of a large cupboard. (DEC was acquired in 1998 by Compaq. Compaq merged in 2002 with Hewlett-Packard.)... 

In both instances Bos employed a Digital Equipment Corporation PDP 11 computer on-line with a Radiometer polarographic stand with drop-life timer, a three-electrode system (DME, reference and Hg pool), two A/D and three D/A converters, together with a DEC writer and a recorder. For the "computer polarograph he used a Radiometer P04 polarograph and an external clock, and the computer had to perform the following functions ... 

For example, there are numerous military and defense-related systems, including administrative systems which assist in formulation of acquisition strategies and the development of relevant documents, battle strategy systems, and hardware maintenance advisors. Other successful administrative applications include a system used by the IRS for selection of audit candidate tax returns, and a credit evaluation system used by American Express. Successful systems in engineering areas include the XCON system which assists in configuration design of DEC (Digital Equipment Corporation) computer...

In September of 1983, a female employee at DEC s (Digital Equipment Corporation s) semieonductor plant in Hudson, Massachusetts, indicated that she felt that there was an excess of miscarriages occurring among employees in the lab clean rooms. As a result of this allegation and the absence of internal data, the University of Massachusetts School of Public Health (Amherst) was requested to conduct a health study that focused on reproductive outcomes but would produce incidence data on other diseases in the worker population, as well. The study was begun in May of 1984 and completed in 1985.
