ABSTRACT:
An external clock unit for use with a DEC MICROVAX model 31 computer includes a first crystal oscillator for generating a clock signal of about 44 MHZ, a second crystal oscillator for generating a clock signal of about 63 MHZ, a 2 to 1 multiplexor for receiving 44 MHZ clock signal and the 63 MHZ clock signal and outputting one of clock signals, a first switch for selecting which of the two clock signals is to be outputted by the 2 to 1 multiplexor, a second switch for selecting which one of two logic signals is to be outputted by a system identification code generator in the computer and a power supply for providing power to the device. In use, the external clock unit is connected to jumper pins on the processor clock signal line and the system identification code generator.
