I'm trying to understand the various disassemblies and such and figure out

how the data translates...



The table in HELLO.LST contains values that, in order, go into

and the last number into a counter which is decremented.  But some of

these values don't appear to make sense with my current understanding.



1. "Sector" values that exceed 16

2. Addresses in the ROM space, when analysis shows the ROM is never used



So I'm parsing the table wrong...

Look at Beneath Apple DOS, pages 6-5 and 8-35. $B7E8 is the start of the RWTS parameter list; $B7EC/ED is track/sector; $B7F0/F1 is the buffer lo/hi.

...that's exactly what I have noted...
