A friend of mine has pulled the rev counter out of his Citroen 2CV and wishes to rescale it for another car. This counter is analogue and includes an 8-pin DIL IC with the TI logo on it and is dated 7725. It must be a charge-pump/accumulator/sort-of-thing, but the oldest databooks here at Brunel University only go back as far as 1979, and type 76810 isn't mentioned; however, *most* of the chips with those sort of numbers *ARE* fancy psuedo-analogue IC's such as freq-to-voltage converters & the like. If anyone out there at TI (or indeed anywhere else) knows whether data sheets for this thing are still available, or if anyone has one or knows where I could find one, I'd be grateful for some e-mail. A chip is not much use if you don't know what it does ! Thanks in advance for any help, Martin -- - /| . . JCXZ ! MOVSB ! SGDT ! iAPX ! | "Good morning Citizens. I would \`O.O' .
