In order to upgrade your system with these EPROM chips, you must configure W102, W103 and W104 as follows:
I suggest you to replace PCB wire links / zero-ohm resistors with pinheaders, so that you gain a flexibility to switch between different EPROM types. Once these jumpers are set accordingly, simply replace your current ROM chips with new EPROMs. Note your new chips are labeled (HI) and (LO), make sure you insert them in corresponding sockets, labeled same way.
