Does anyone have a copy of the MKII service manual or schematic? Because that would be a big help in working out if the kit could be fitted into it. I once saw the inside of a Poly 800 MKII and it had a much larger ROM installed and a totally brand new board where the ROM lived. The ROM socket on main board had jumper cables running over to the new board. It was quite a mess. The schematic diagram of the MKII would put the question to rest.
