The 244 images come from photos, slides and brochures from the mid-1970s in the case of highway trucks and from the early 1980s for the off-highway vehicles. Two well-known truck builders,. Kenworth and Peterbilt, are still around, all three U.S. automakers have exited the large truck market and two builders, Brockway and Marmon, are gone.
An aspect of the 1970s era were the cab-over-engine trucks that went away with the easing of truck-trailer length restrictions. In the mining area, the trucks of the early 1980s were almost half the capacity of contemporary trucks.
The presentation is like looking through a book on a computer. The CD-ROM works in PC's (WIN 2000/XP/Vista/7) and Macs and is self-starting. The images can be printed out.
