When you say it only works in 16k mode, was it functioning perfectly before? or have you altered anything to obtain this fault? Link 25 is the RAM Select link. As you say, NORTH is 32K mode and SOUTH is 16K mode. The reason Im asking this is you say, if you move link 25 north, well it should be there anyway. Any more info you can throw at us? Rich. |
