Right, you don’t need TS-DOS, but you need *something* with the ability to load files from a TPDD compatible device. If you have an actual TPDD, you can use the bootstrap function, otherwise you have to find a program that can be used to bootstrap the necessary files.
That was the challenge - finding a program that could do the job on the T200.
