I'm trying to add another Apple II clone mainboard ... if I just re-use another chargen ROM, the text is readable, but this is what I get if I add the ROM that came with the mainboard.

It looks like the bit order is reversed, and one column is missing.
Is this necessarily a bad dump, or is there a ROM loading parameter that'll correct this presentation of data?
