### IDC cable
You need a cable to connect both boards
Any straight IDC-20 cable should work (pin 1 to pin 1, etc). Macintosh floppy cables are compatible. We used a Quadra 800 cable for prototyping (Apple P/N 590-0862-B).

- PowerMac 7200-7600 (Apple P/N 590-4529-A)
If you are looking for a new one, a compatible assembly is made buy Advantech under the part number PCL-10120-1E.
## PCBs
the PCBs are simple 2 layers boards. The gerbers are avaible in the release section.
Check for the following files:
* TTT_11.zip: main board revision 1.1
* TTT_12.zip: main board revision 1.2
* DB19_IDC20.zip: adapter board revision 1.0
You should be use any mainstream PCB manufacturer for theses. Nothing special about them. PCB thickness should FR-4 with a 1.6mm thickness
