Complete OPD ROMs, in case anyway fancies making an Emulator!

Small development, found a YouTube video about reading an 8051, they suggested selecting an Atmel AT89S53, and it worked, only thing thing is that the AT89S53 is has 12K of rom and the 8051 has 4K, but I trimmed it and compared it to what I got from the 8751, and it was identical, except for some junk at the bottom that wasn't there on the 8051.
I'm not sure how they squeezed it in, but they must have done it somehow.

Next thing is to desolder the 8051 from the printer module and see what comes from that...
