The invention provides an arrangement for time correlating a computer\s internal information with its input and output signals. The internal information is stored in a storage device along with time data indicative of the time at which the internal information was read. This time data is used to correlate the internal information, when read from storage, with the input and output signals. The invention also provides a more general arrangement for producing logic signals. Data for producing logic signals are stored in a memory. This data includes a transition time and a corresponding logic level after the transition. Logic signals are generated and “forced”to the logic level called for by the data read from memory. This allows logic signals to be produced from little data. This general scheme is applied to an arrangement for recording and reproducing digital and analogue signals. Digital data is recorded in memory and “reconstructed”using a single, common, clock is used for A/D and D/A converting to insure synchronism over a long period of time.

A method of time correlating at least some of a computer\s internal information to at least some of it\s input and output signals, comprising the steps of: measuring at least some of the input and output signals of the computer; detecting the real time when the input and output signals are measured; storing measured values of the input and output signals together with their corresponding detected times into an external storage device; reading at least some of the computer\s internal information; detecting the real time corresponding to the reading of the internal information; storing the internal information together with its corresponding detected time into the external storage device; reading from the external storage device the previously stored internal information and input and output signals together with their corresponding reading times; and displaying the information read from the external storage device in a manner which time correlates the internal information with the input and output signals based on their corresponding detected times.
