The rom board has 8 rom slots which can be individually enabled using the dipswitches.A link allows the roms to use the ids of 0-7 or 8-15. 0-7 is compatible with the firmware in the 464 which is limited to 8 roms. 0-7 or 8-15 is compatible with the firmware in the 6128 and Plus. NOTE: Some 6128's may not support ROM 7 being overridden so if you use the range 0-7 then you should disable slot 7. Testing was done by user ngroom on his Rombo Rom board. The I/O port decoding used to select the rom (dfxx) is partial decoded partially and only checks A13=0 onlylike other rom boards. ROM ids are 8-bit and fully decoded. The board has a link on it which controls if the rom If range is 08-7 (compatible 15 is selected with 464, and where ROM 7 the link then you see a rom in slot '0' in 8 only. It is not AMSDOS, and 8-15 for 6128)show in any other slots. I.e. it's not repeated.
