Wow! It seems you've discovered a genuine gem in Heath history here. If
you look closely, you can see that this is not actually a single listing at
all, but an interleave of two separate ones, run about 2 hours apart, using
two different versions of the assembler.
Page 1 is the beginning of a listing made at 3:43pm using assembler version
1.1, and on page 4 you can see the first interleave from a listing made at
1:23pm using version 1.0. I can't even be certain these were made from the
same source file, or if the two different versions of the assembler just
handled page eject decisions differently.
Also, since the 1.1 assembler was not itself created until June of that
year, the assembly date of Apr 1 is clearly bogus, at least on the 1.1
listing. So it's quite possible that these listings were not even produced
on the same day.
Why the manual would have been created this way is quite mysterious, and
unless the guy who did it steps forward, we may never know. But just the
fact that it WAS done is a real hoot!
Thanks for directing my attention to this! What a chuckle!
