hi guys i was hoping someone clarify something for me. With the application note for at89s51 isp it shows you how to make a cable to connect to the spi interface. To program at89s51 with isp.It also say that the other side of the cable needs to go to the printer port on the computer. But it does't give you the pinout for where the wires have to connect to the printer if someone could help i would be greatful.
