> Extended Temperatures.
AFAIK there are versions of PowerPC 750 and TSI107 with extended temperatures from -40 Degree C to 85 Degree C. IMO this specification is sufficient for automotive / car (inside the dashboard) applications. There is also a MIL STD 883 version, but it's rather expensive.
But first Troika should provide details of the company (address, fax, phone, history, reputation, warranty, availability etc).
