Now this is what information access is all about! I’m cleaning out my office and chucking large numbers of older reference books. But what if I can’t find some again! I still happily clack away on my beloved HP-28S, which stems back from 1987-1988 for me. Well, here is the manual! Nice job, HP. Little cost to you and a great boon to people who have purchased your products. Good karma from my hosting the manual for the KORG MT-1200, which I still get hits on!

The Silver Medal was presented to Don Lebeuf of Oakville and his Plum Crazy Purple 1970 Dodge Charger R/T SE, which took eight years to restore. And the Bronze Medal went to Steve Huck of St. Catharines, whose two-tone red-and-white 1958 Ford Fairlane Retractable, with a roof that disappears into its trunk, was brought back to showroom condition from a wreck.

The Cruise Nationals were created to celebrate automobiles and the people who are passionate about them. The process that brought 10 cars to the 100 Level in the North Building of the Metro Toronto Convention Centre for the Canadian International Auto Show (which runs through Sunday) began with the first of 10 events held as part of summer “cruises” last year in Southern Ontario.
