I'd found the C version. The comments on the globals helped a lot. Z, the 
thrust per pound of fuel is arbitrarily set to 1.8. I'm not sure about 
setting G (gravity) to .001.  As a game it doesn't make a difference but I 
don't think it's correct.

I worked with a PhD chemist with a similar style but he used FORTRAN. 
Unraveling it and converting it to 8049 assembler for a handheld device 
was interesting.
