Part 1.
Today I started a project that will be the "Hard Way" to get the Macintosh SE on the internet.
For this part of the project, I have created a serial (or null modem) cable.
I have butchered a Macintosh printer cable for its connector housing, and a generic Sega controller for its cable, that actually has all 9 wires.
(I had a serial cable but after stripping it down, it only had 3 wires. The Macintosh cable didn't have all 8 wires either.. That's why I only got to use its connector.)
Had to use the multimeter and a battery to test which color wire went to each pin.
Wasn't hard at all.
Above, these are how the wires need to match up from one end of the cable to the other. On the Mac end, looking at the cable, just do it backwards. My diagram shows the back of the computer.
The connector is ugly but it works and goes in and out pretty smooth. The middle pic above is a test fit before I finished the connector off.
Now that took me a few hours to take my time and make sure I got it right. The real "Hard Part", for me at least, is going to get the appropriate software onto the Macintosh. Using this cable will allow the Macintosh to "Dial-in" to a linux/unix computer with a serial port, running PPPD.
I will post more when I get it working, in Part 2.
Thanks for looking! :I
