Dolch FlexPAC Portable Add-in Computer
I worked for Dolch computer systems while the FlexPAC was in development, and remember Volker Dolch agonizing over every design decision. He had a great eye for detail (not the glass one) and really knew how to push the development team to make it quickly, but right. The casing was a glass-reinforced plastic over an aluminum chassis, and stood up very well in practice. The Kontron logo in the background of the image above jars with me, as I left Dolch before Kontron (my first employer) bought them.
I bought one recently on eBay and was a bit dismayed to find it was one of the six slot versions which were considerably less elegant!
Also notable from the time was the VP of Marketing coming up with “Turbulent flow cooling”. It had a fan on the back.

High Performance Portable
• Full Length 4x PCI Slot
• 14,1” TFT Color Display
• Rugged Construction
• Operating Shock 10 G, 11 ms
The Dolch FlexPAC is the most space-efficient, easily expandable portable conceived.
More computing power than most desktops is ingeniously integrated into a case measuring only 10.18-inches high, by 6.72-inches deep, by 15.78-inches wide, and weighing 18 pounds. Power and flexibility are assured by the four full-size add-in slots, up to five drives, and a large high resolution active matrix colour display. For the ultimate in portable performance, FlexPAC utilizes the Intel Pentium® IV microprocessor running at 2.4 GHz, with 400MHz FSB on the Intel 845 with ICH2 chipset.
Making use of Dolchs time tested, shell-within-a-shell packaging technology, FlexPAC is ruggedized well beyond anything else in its class. The outer shell is an injection moulded, fibre reinforced polycarbonate composite – a material exhibiting a higher strength to weight ratio than steel. The inner shell is crafted from aircraft grade aluminum. Ingenious cooling baffles can direct airflow where it is most effective, and double as un-compromised card hold-downs. FlexPAC is an ideal platform for high-end, mission critical applications requiring substantial add-in capability for boards and peripheral drives.

Dolch badged their products for many third parties, creating a custom product platform. A lot of effort went into keeping specific configurations available for as long as possible – quite unlike the retail marketplace. When you have to certify a product due to platform changes it’s an expensive business. Cherri Nelson did the diagrams
