I've separated your ROM dump in its three 8K parts and preliminarily inserted them in my local MAME source ... the language part is identical to the Rainbow A ROMs we have in the driver, the emulation comes up with the other ROMs from your dump, but hangs after the printer/comm port error message ... probably the ROM patches have to be adjusted to the earlier code.
