I finally got my Apple IIc

I recently (as of July 2001) rescued an Apple IIc computer from the sidewalk, which resulted in re-discovering this classic computer introduced April 24th, 1984. To make a long story short, I always wanted to own an Apple II computer in the old days, and now it seems destiny put it in my way 🙂

The information presented here is a small account of my findings, and includes some of my own contributions and additions to the resources I have found. Important: I have not tested this in any way, as of August 2001. This information is presented here for self-documenting purposes, hoping I will someday have the time to update it and play/test it. Enjoy!

How to connect any PC to an Apple II


  • An Apple II equiped with a Super Serial Card, a card which is hardware-compatible with SSC, or built-in SSC-compatible serial port hardware. The IIc+ and //c include SSC-compatible serial ports. The built-in IIgs serial ports are _not_ hardware-compatible with SSC and will not work with ADT 1.22.
  • A PC running Windows 98, 95 or 3.1, with a standard serial port, either DB9 or DB25
  • The Apple Disk Transfer program – Apple Disk Transfer ver. 1.22 (ADT122.ZIP, 71KB)
  • A DOS 3.3 formatted diskette – this will be used to store the ADT software
  • A custom-made serial cable which you can make

Windows 98 users will have to replace their current HyperTerminal version by downloading the latest HyperTerminal Personal Edition.

Serial cable pinout

To make this cable you will need:

  • Shielded multiconductor cable (5-wire) (Radio Shack #910-1610 or similar)
  • DB9 or DB25 connector for PC ending of cable, depending on your PC serial port configuration. This is known as a combination of IDC D-Sub connector and housing, must be male of course.
  • Standard DIN 5-pin male connector (Jameco part #15878)

Of course, some soldering equipment won’t hurt 😉
