Removing one of the 8K ram chips from 4000 to 5FFF seems to have solved the issue with corruption of FD00. Iím suspecting the search for the extent of ram for the corruption.

Also discovered I have too many inverters between F2 out and RTS output, I used two as I didnít realise it should be inverted.
