I know. You lost the manual. Normally, that would not be a problem, but the manual had the three lines of BASIC code you need to copy the file management program off the disk and into the Model 100's memory. Thought you'd never ask:

10 OPEN "COM:88N1DNN" FOR OUTPUT AS #1
20 PRINT #1, "S10985157C00AD7EF08B3AS901FE"
30 LOAD "COM:88N1ENN", R
