Info

Two other boxes marked "color display" contained the display hardware. In eachwas an NCR 14-inlch color monitor, an NCR Graphic CRT Controller card, and "kit"instructions ("owner's manuals") for each item. A graphics inemory upgrade was installedon tlne card.Finally, the fifth box contained numerous miscellaneous parts, each packed in itsown box. Included were two tilt and swivel bases for the monitors, two 128K RAMupgrades, two 8028'7 internal arithmetic co~processors, two 360K 5-114 inch floppy (flex)disk drives with headload, two vertical mounts, and two display kits (3-meter video andpower cables). Also in this box were at least four sets of RS-232 communications cables,parallel printer cables, and serial cable converters (DB-9 to DB-25). In the test reportedhere, the vertical mounts and cables were not installed.Performance vvas recorded using a 112-inch VHS video system. It included a SonyS-100 camera, Panilsonic NV-8410 portable recorder, Thalner Electronics Laboratoriesmodel TD-426P timer and date generator, and Panasonic BT-S700N 9-inch NTSC formatcolor monitor. The ciateltime generator output (displayed to the nearest 1/10 of a second)was superimposed on the scene being taped and was recorded with it. All video equipmentwas mounted on a vvheeled tripod, and the monitor was facing the participants, so theycoulcl see the camera's field of view.- Test Activities and Their SequenceParticipants were videotaped while setting up an NCR PC-8 using the "subjects-in-tandem" method described earlier. All testing was carried out in room 337 at theUniversity of Michigan Transportation Research Institute. A well-lit 15 x 15 foot openarea was used for tests, with assembly taking place on a standard 60-inch desk in thecenter of the work area. On a few occasions where it was unclear what the participantswere doing, the camera operator asked them for an explanation.There were three work periods in this experiment. In the first, the two testparticipants cooperated in setting up a PC-8, discussing problems as they went. The firstand third sessions were recorded on videotape. Activities taking place during the firstsession included unpacking the system shipping box, removing and installing the keyboard,installing the 128K RAM upgrade and 80287 co-processor, installing the display adaptercard, and attempting; to install a 360K floppy drive (Green, Ottens, and Reifeis, 1986).The {session ended after an hour and a half when the participants were unable to installthe disk drive.
In the second work period (for which no data were collected), two NCR fieldengineers (Norm Cook and Sam Griffith) tried to install the 36OK drive. Both spent 112day (on it without success. Sam subsequently returned and spent an additional 1/2 daycom~lleting installatioln of the disk drive and installing some of the system software. Thefield engineers had ni~t received specific training on the PC-8, though they had experiencewith other similar products. Because the PC-8 was a gift, the NCR procedure to identifytraining needs for its field engineers had not been triggered.In the third se!ssion, the two subjects installed the display monitor base, put the feltfeet on the cabinet, checked the key lock, copied a DOS disk, formatted the hard disk,installed DOS, and copied system and utility files from a floppy disk to the hard disk. Thatsession lasted an hour and a half, and was recorded on videotape (Green, Ottens, andKrusic, 1986).
