I thought it was not to do with the code - more the fact that in order to
provde 156K more RAM than the old 512K expansions, they used up the ROM
space - certainly I have no EPROMs which will work with the Trump Card.

I did not though realise that TC could not read standard roms.

I might be wrong there, thinking about it.
