Adding to the seemingly confusing versions and revisions situation, there is another EPROM that looks like a derivative / evolution of the initial ones. That's the -MLEPROM_1H, which contents are shown below. The XROM# is also different, #4

I've been looking into the code for this last one in more detail. It *assumes* that the X-Functions module is plugged in page #8 and makes direct calls to addresses in that page, not a good practice but I understand why they did it back them. I have converted many of those calls to a CX-based schema, with the exception of cases were the routine called is in the bank-switched page #5 - this makes two functions unusable, "SUB$" and "KEY".
