BTW, Radio Shack did publish the ROM calls available in the Model 100
in two different publications:

	Model 100 ROM Routines
		(700-2245)
		Radio Shack
and
	TRS-80 Microcomputer News
		Volume 5 Issue 11
		November 1983

Both lists are approximately the same, inluding descriptions of the
ROM routines (minimal descriptions) with caling sequences and
returned values.
