Hi
That page is full of bugs. HC11 have no BDM, so Multilinks and Cyclones have nothing to do with it.
Freemaster I think appeared first much more later than HC11 became not recommended for new design.
If you need debugger, then look at www.noicedebugger.com. For C compiler try visiting www.imagecraft.com, though it's not easy to find SW tools for old HC11 any more, here's direct link http://imagecraft.com/legacy/devtools_FreescaleOther.html . There were more expensive compilers from Cosmic Software, Metrowerks, IAR. Unless they've changed the price, I double they could be feasible to start HC11 now. There was GCC port for HC11, perhaps try looking for it first.
Regards
Edward
