I have located OS-9 L1 disk images for the SWTPC on the online for an 
SWTPC I'm very slowly restoring.  The disk images run in an emulator, 
and of course I can peek at them with a CoCo.  I've determined that 
these were somebody's working copies, rather than straight images of the 
original disks.  But I could check and see if they have SysCall.
