OK, I've looked at the stock Tandy disks for cat# 26-3030, 26-3036, 700-2331 
which includes Level1, Basic09, and Level1 vr2. None of these have syscall.

The only place I've found syscall is on the Level2 26-3031 Boot/Config disk in 
the CMDS directory. It is not on the System Master disk.

Since there is no source code, the code in NitrOS-9 clearly is from a 
disassembly. You would think that it ought to be listed in the index for the 
Level2 Owners Manual in the Technical section but it isn't. It is mentioned in 
the Basic09 section where syntax is discussed. There is no mention of it being 
on the second disk in the Level2 set.
Examples of use are given in "The Complete Guide to OS-9 Level2 Vol1" by Puckett 
and Dibble. No source code.

I can send you the program from the Tandy disk for disassembly and you can 
compare it against that in NitrOS-9.
