Hi, folks! When I wrote my last mail about this matter, I stated the ProFile attached to the computer via a standard Disk ][ drive port. I was wrong. It really attaches via the Apple /// or Lisa parallel port. I have been doing some research in the web and I have realized this, as well as other things.
The Lisa/Apple /// parallel port is a DB-25, like the PC one, but it has different signal distribution. This has two reasons. First of all, the Apple /// was released at about the same as the original IBM PC (the one with 16 Kb of RAM). And second, the original PC parallel port was unidirectional, while the original Apple /// parallel port was already bi-directional. Ok, I'm going off the topic. You can see the pinout of the Lisa parallel port (it's the same as in the Apple ///) in http://www.cs.swarthmore.edu/~tom/cs23/final/ , just bellow the title "The ProFile Protocol". The guy that asked the question said he had a flat 25-pin ribbon with the wire from pin 7 cut off. As you can see in the schema that is in the previous page, the pin 7 is the only not connected pin. So I guess the cable is right. I hope have been helpfull. Now I'm going to talk about another matter, so I'll start another mail.
