It seems that configuration wasn't used.
"Phase I: The off-the-shelf system
The closest approximation to the intended workstation environment
economically feasible on available Digital hardware at the time the
project began was minicomputer time-sharing systems. Approximately 50
VAX 11/750 minicomputers have been installed, each with six to eight
The closest approximation to the eventual workstation configuration
available in the IBM catalog for Phase I was the PC/AT personal
computer, with a Professional Graphics Display and 3COM Ethernet
interface. Approximately 160 PC/AT's have been installed. The software
environment consists of PC/DOS, plus a set of higher level languages and
application packages chosen to simplify moving to an eventual UNIX
environment. In addition, 105 PC/XT personal computers, mostly with
Color Graphics Display, have been installed, primarily for use as
laboratory experiment controllers and also as cluster print servers for

Multiple companies made these kinds of cards.
