Hello, Gurus! I need to write a value into a PIA, and then write a different value about 145 uS later. Is there a sensible way to time such a delay on the 9010A, or do I have to use a delay loop? For the curious... this is to test the interface to a Bally Squawk and Talk board, from the MPU board. Thank you for any help, Mark Templeton _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
