Not sure if it's relevant:

My brother was one of the few engineers on this product, in Palo Alto. The software ran on dozens of different machines and architectures, using the most portable language of the day: Fortran 77.  I believe MARC was the umbrella name/company for a number of different products. 

He got me a summer job there - I had to print out the sources and then make copies for everyone. We also wired the offices with rs-232 runs to the PRIME lurking in the basement.  

Formative years...
