McLaren Needs A 20 Year Old Compaq Laptop To Maintain F1 Supercar
McLaren needs a 20-year-old Compaq laptop to maintain its F1 supercar
McLaren's F1 supercar is special in more ways than one. Even now it's still the world's fastest production car with a naturally aspirated engine, and McLaren only built 106 F1s in total.We visited McLaren recently, and discovered another special aspect to the F1: a 20-year-old laptop. McLaren is still servicing the existing 100 F1s with a Compaq laptop from the early ‘90s.
"The reason we need those specific Compaq laptops is that they run a bespoke CA card which is installed into them," explains a McLaren spokesperson.
"The CA card is an interface between the laptop software (which is DOS-based) and the car." If you've never heard of a CA card, Mike Herbst helpfully explains it's a Conditional Access card. Modern PCs use smart cards or USB keys with special access codes to access sensitive systems, and the CA card was used as custom hardware as part of an integrated system for security and copy protection.

A standout feature of the F1 was its central driving position
It is one of the most remarkable supercars ever built and twenty years after its launch McLaren's F1 still fascinates like no other. In this episode of evo Diaries evo Magazine's Henry Catchpole introduces you to the devilish detail of the McLaren F1.
