In the beginning, there was the Marty Goodman Document, and it was good.

More recently, Rick Shear has taken a new and very careful look at a real cable, and the Marty Goodman doc, and has probably identified the "mystery" components that Marty Goodman talks about. It looks right, and this cable does indeed work.

Rick's Initial post
Rick's Follow-up

Build one without destroying an FB100 cable

This is Ricks original PCB, with parts and directions to build a cable where:
  • The DB25 backshell is a special type that actually fits in the Model 100/102 serial port opening.
  • The TPDD connector is made with a standard "Dupont" housing, instead of having to find an irreplaceable old real FB100 cable and destroy it.

Refined version of Rick's PCB

This is all the same parts, and all the same work as the cable above, merely the PCB is redesigned to be as compact as possible, leaving more room inside the backshell for wires and cable strain-relief.
