Power Supply Circuit Description

The CP-3 has an internal supply which produces the required DC supplies Overview from various line voltages. It may be strapped for line voltages of 100,120, 220 and 240 VAC at either50 or60 Hz. All DC voltages are produced by linear supplies. A bipolar 15 volt supply is required by the analog electronics and is regulated locally on the lower analog board. The digital and video electronics each require +5 volts. One regulator, located on the power supply board, is used for both supplies....

CP3 ROM Address Space

System ROM space. kXVI Jumpers W1 and W2 IN. System ROM space. KXX1 Jumpers W1 and W2 IN or OUT. Overlapping ROM space allocated for system code and diagnostic reset and interrupt vectors. V , Jumpers W1 and W2 OUT. Diagnostic code ROM space. This figure shows how the physical ROM space is split between the Diagnostic and System code. Shared space is used by the System code, except C000 -C08FH which is reserved for Diagnostic code Reset- and Interrupt- vectors. Master...

Return the Variac to nominal AC line voltage. 3. Return the Variac to nominal AC line voltage. Power off the CP-3 using the rear panel power switch. Measure the battery voltage at U33 pin 28 to ground and verify that it is > 2.50 VDC. Power on the CP-3 using the rear panel power switch. Alternately set the Variac to both extremes of the AC line voltage operating range given in Table 4.2 and verify that the regulated supply rails remain within their tolerance range. Then, return the Variac to...

Z80 Diagram Blocks

During normal operation, sampled audio is converted into digital data by successive approximation A D converters. Digital effects processing is performed by the Lexichip under the control of both Master and Slave Z80 processors. The Lexichip controls not only the effects processing, but also the Analog-to-Digital and Digital-to-Analog conversions. The Master Z80, which handles all operator I O and housekeeping functions, is able to pass DSP control information to the other two processors. The...

The iR Receiver Interrupt Timer circuitry 2 D6-D4 generates the interrupt IR Receiver pulses INT , 2 D3 for the Master Z80. The INT signal is connected to the Interrupt Timer Master Z80 Interrupt. This circuitry is driven by the Lexichip Word Clock signal WC , 4 A2 . WC is a pulse signal which appears at the same frequency as the sampling rate for the audio signal. The frequency of the WC signal will, therefore, vary depending on which program the CP-3 is running. All of the Ambience and Reverb...
