I'm up for that! However, only if the resulting C program can be compiled/run
on a V6/PDP11 again.

Let's assume that reverse engineering a subroutine of 20 lines takes
an hour. That then makes for 100 hours. If 10 people participate and
contribute one hour/routine per week, it will be done by May.

However, the initial analysis of the code architecture is a (time) hurdle.

PS: the Fortran66 of V6 is also assembler only...
