The CF-M34JA8S, which runs Windows 98, and the CF-M34JA2S, which runs Windows 2000, are designed to be used under rough working conditions.
Like the other Toughbook models, display and keyboard parts are resistant to water drops and dust and can survive being dropped from heights of up to 90cm.
The CF-M34 models measure 229 x 188 x 43 mm and weigh 1.8 kilograms. This makes them slightly smaller than the previous CF28 model and about half the weight.
They also feature an 8.4 inch colour TFT LCD display 8 and SVGA 800 x 600 pixel SVGA resolution with an anti-reflection coating that allows use under direct sunlight. The display also features a touch panel.
The CF-M34 models have a Pentium III M-700MHz processor, 20Gbyte hard disk drive and an IEEE 802.11b module for wireless LAN connectivity. The battery lasts for 4.6 hours with the CF-M34JA8S and 6 hours with the CF-M34JA2S.
Matsushita will launch the products in Europe on 14 February. The suggested retail price is around £1,400.
