These are scans of a 'work-in-progress' port of HAL70 into HAL75.  (HAL70
is the Interdata-70 code generator; HAL75 is for the ICL 7502 RJE/Editing
station).  With a fix to one line, it does actually compile but without
any test files or a predef file, we have no real way of testing it.  We
do not have an emulator for the ICL7502 nor any documentation (although
there may still exist some documentation in other peoples' archives such
as UMIST, or ICL)

This was almost certainly later ported to run on the Interdata hosts,
followed by conversion to HAL which would run on the 7502 itself.
(Although we need to check with Hamish to confirm that)
