$75,000 is a bottom ~15-20% software developer salary in the US today per the BLS figures.
Someone in his ability range today will earn twice that (Gates was clearly at least a top 25% programmer in his day, more likely solidly top 10%), or more depending on location. That's before factoring in the age & experience issues, which can throw that all over the place and would be hard to adjust for today vs 45 years ago.
