The disassembler I use (an old version of IDA) is interpreting everything as one segment but it's clearly using two. There are some places where the code, or the order of the code, of the 8088 version does not quite match the Z80 version and I lose synchronization. I tried another approach - to attempt to hand-convert through search-and-replace the Z80 code - but that hasn't worked either. -uso.
