Starting with zero knowledge of Joerg's platform I wrote an RK11/RK05 emulation in about a week. MSCP took longer (about a month), but that was entirely due to the complexity of the MSCP spec. Joerg has done all the hard work here and has provided a really useful set of tools for building device emulations. I hope to have some time to do a few more devices soon -- TMSCP is on my list, along with TC11 and RX11... I'm taking requests if anyone has 'em :). - Josh > >
