Cool! I was able to recover the code and convert it into a more modern
PAL dialect. Your listings also don't display the many literals that
were generated on page zero (except sort of implicitly).
In making the page zero literals line up (so that the code matches the
originals), I found two locations in xmtape which are coded as
TAD (16.
but the code references a new literal at location 0161, instead of the
previously generated one at location 0166. This is at location 0567 and
again at 0666.
(In the PAL assemblers, the "(" must be a "[", you can't use "." to
change radix, etc. etc.)
