Looks quite similar to a Cassini projection with the 75° E meridian as centre instead of the 0° meridian.

but why tf is the equator not in the center

This is also the first portrait map I've seen, too. Really novel design choices here (why centre just south of India?)

The equator is one centre axis, one meridian, here 75° E the other. Thus, 0° N 75° E is the centre here instead of 0° N 0° E.
