Zip file contains 2 discs. This program cannot be run without the hardware protection "dongle" that plugs into the HP-IB port. These dongles can be made using the connector end of an HP-IB cable, 2 diodes and a push button switch. Start by removing the connector end of the HP-IB cable from the cable itself (we used a hacksaw).
Instructions for making the Diagraph dongle:
(1) connect the CATHODE end of diode1 to pin 15 (DIO7) of the 24-pin connector.
(2) connect the CATHODE end of diode2 to pin 4 (DIO4) of the 24-pin connector.
(3) connect the ANODE ends of both diodes together.
(4) connect the ANODES in step 3 to one side of the pushbutton.
(5) connect the remaining side of the PB to pin 10 (SRQ) of the 24-pin connector.
