My interest is I have a S/36 with both TwinAx and SDLC.  SDLC is a lot 
easier to interface to.  But I have built a electrical interface board 
to go from a balun'd RJ11 twin-ax interface to an FPGA with the intent 
on eventually building an open-source TwinAx <--> USB converter.  Sounds 
like there's a lot of interest.  If anyone is wanting to help or test, 
I'll move this up the priority list.
