The tight fit of the p.arts made removal even moredifficult. Both an illustration and some place to grasp the bottom would have saved abouta minute in this experiment.There were no problems with insertion of the graphics card other than someconfusion about which slot it should go into. A remark about slot choice is providedsome,where in the insl;ructions, but it appears too early to be remembered.Participants were unsure if the correct card was provided, because it didn't have aname on it. (They were also unsure if the factory-installed daughter board was the serial/parallel adapter. It wtas.)The next sequence of steps involved finding and unpacking the options to be installedin the main cabinet. (See Table 6.) A large fraction of the time was spent figuring outwhat the next step was. Again, this problem resulted from the multiple pieces ofdocunnentation being used.Installing the co-processor, a task that consists of removing a socket cap andinstalling one chip, took eight minutes (See Table 7). As with the previous tasks, therewere problems with understanding the instructions (and which instructions to follow) aswell iks a lack of illustrations showing where pieces go and how to install them. Alsolacking were tools for removing and inserting integrated circuits.The 128K RAlM upgrade took 8 minutes and 20 seconds to install. Here theinstru.ctions were reasonably good. However, of that time, about 2-112 minutes werewasted removing and then re-installing the graphics display board (See Table 8). The
