I know that ROM0 gets paged in at 0000-3FFF and ROM1 at C000-FFFF in the z80's memory map, but I wasn't sure how the two were held in the actual ROM chip. If A14 of the ROM is connected to A14 of the z80 then ROM0 is at the bottom, but if the ROM's A14 is provided by the ASIC then it may be a different story. I suspect it's directly connected to the z80, though (don't have my technical manual with me any more....) Andy
