First, If you try some of these connections WATCH OUT.

Don't always believe what you read. The pins connection on the Apple
products are correct. Making the connections are a whole different
story.

Do you plan on sending data or what? You need pins 2 and 3 (transmit
and receive) Also the super serial only has 1-8, and 20 (it might have
one more). Pins 13,19, and 23 are non-existent

There is no such thing as true modem eliminator (This cable also works
between Ibm serial and a Imagewriter I. You need to make a different
cable for Lisa to Imagewriter I (I have the specific, I will post them
later if someone wants them)

Since I have wrote this at a busy moment I will have to follow up
later with some accurate information.

You can read as books as you want, but you will learn to love a
breakout box when you make connections between serial interface
computers [make DB25 end to DB25 (DIN-8, DB9, DB50, whatever) with
transmit going to transmit, receive going to receive and so on
(basically a straight thru)] and have fun finding the right connection
between computer-breakout box-whatever.
