There is a hidden set of characters in the original PROM. It was pretty funny to discover it.

I was wondering if you reversed the logic levels when dumping because that effectively flips the map horizontally and vertically,. When that is accounted for it's an ASCII character map between 32 and 95, printables for the control characters and Cyrillic for the lowercase characters. Cool project BTW. Almost wish I had one to modify.
