The in-car microprocessor module allows the conversion of a standard Scalextric car to work on Scalextric Digital layouts.
C7005 is designed to fit most F1 style cars. Some F1 cars chassis produced between 2004 and 2007 have mounting points for this specific chip.
C7006 is designed to fit most saloon style cars. Some saloon car chassis produced between 2004 to 2007 have mounting points for this specific chip.
However, either can be used if room inside the car body permits.
Most Scalextric cars, from 1957 to current date, can be converted to digital operation.
The conversion requires hobbyist skills and some tools including a soldering iron.
For Digital Plug Ready Cars (DPR) use C8515 Digital Chip (Easy-Fit) or C8516 F1 Digital Chip (Easy-Fit)
