That looks to be a rather neat RAM board actually. The regular 41256 chips are 16 pin 256kx1, and the only real option is to piggyback another 512KB on top of the existing. That board takes 18 pin chips which means you can use 421000 (511000 in this case) which are 1Mx1. So, that should be a 2MB RAM upgrade.
