The Tektronix 021-0206-00 GPIB interface is a microprocessor-based interface to connect the 7704A/P7001 digitizer to a GPIB controller.

It plugs into the interface slot on the rear of the P7001.


Due to an error in all versions of the firmware, pin 9 of U123 is always configured as an output pin. This pin is directly connected to an output of the line driver IC U321. To prevent damage to the PIA chip, it is recommended to remove the line driver U321. Since U321 is only needed for internal testing, it can be removed without any problems.
