Dolch Pac 486
Dolch has been making high-quality portable computers since 1987 that can also take a beating. This Pac 486 is an early example.
It is one of the first, if not the first, available computer with an 80486 processor on the market. The original was released in November 1989. This had a 80486SX at 25 MHz and it is unclear when the DX came on the market.
This particular machine has been used by Libertel (now VodafoneZiggo) to measure the strength of GSM signals. The software is also still on the hard disk, as well as all expansion cards.
Striking is the color screen and the rare clicky keyboard, in addition to the fact that the machine also looks very beautiful.
