No I havent, other than mobile (HHTs). From installing other POS types I have had to install MSXML6, dotnet 1.1 a SQLExpress (for SQLServer client).
Looking at the docs for MC50, 55 & 70 there is an OS, a platform file and then CAL. I guess these are all packaged into the nk.bin. .bin There are nk.bin packagers out there, but really I dont know anything about them.
If you need hex files for these things above, I can put them up.
