The main Contura series included models 3/20, 3/25, 3/25c, 4/25, 4/25c, 4/25cx, 400, 400C, 400CX, 410, 410C, 410CX, 420C, 420CX, 430C, and 430CX. These were standard-size notebooks, not ultraportable subnotebook computers. The “X” designation denoted an active matrix screen. The Compaq Contura Aero 4/25 and 4/33c were among the earliest
subnotebook computers that acted as a precursor to
netbooks. They were released in 1994 and originally ran
MS-DOS and
Windows 3.1. They were also able to run
Windows 95 after its release in 1995. Furthermore, they were similar to the
Armada line of laptop computers, but smaller. Although the 4/25's GPU can produce color, the datasheet for the device states it is incapable of producing color graphics. This does not apply to the 4/33c. This line of notebook PCs from Compaq was first succeeded by the
Compaq C-Series and then by the
Aero 1550 Pocket PC. The line of handheld devices starting from the
Aero 1550 Pocket PC were finally moulded into the
iPAQ line of handheld devices, which was handled by
Hewlett-Packard, after their acquisition of Compaq. == References ==
