Humm, didja try my vfy?  Something must have contaminated your verify, or 
your rel.  Better yet, I just tried my copy of verify on one of the 5 rel's 
in the dw3 .dsk install, it didn't crash my coco, but it hung it will I hit 
a key, then returned with an illegal module header error.  That I expect is 
because it probably needs a legit $87CD as the first two bytes, and rel 
doesn't have them and never will because it has a 6 byte rsdos leader.

A dump looks like this:

Address   0 1  2 3  4 5  6 7  8 9  A B  C D  E F  0 2 4 6 8 A C E
-------- ---- ---- ---- ---- ---- ---- ---- ----  ----------------
00000000 4F53 202D 1205 87CD 012A 000D C185 D700  OS -...M.*..A.W.

Note the rsdos binary header, so the $87CD starts at offset 6.

vfy will show you this:

{t2|07}/DD/NITROS9/dw3install/6309L2/MODULES/BOOTTRACK:vfy rel_80_50hz

Length of file: $00000130
Module found at offset $00000006 in this file
Header for    : REL
Header parity : $D7 (good)
Module size   : $012A
Edition       : $05
Ty/La At/Rv   : $C1   $85
System module, 6809 object, Re-enterable, R/O
Exec. off     : $002B
Data Size     : $0000
Module CRC is : $3F6405 (good)

Bytes read    : $00000130

vfy is a multi-bladed swiss army knife.  Check it out.  It should be on my 
web page. The CoCo-os9-stf link I think. 

Cheers, Gene
