I am using the Mathias ICE with the PIC16C76 family pod. Pins RB3 and RB4 will not pull low when connected to a light load (Data input of LCD display). If I connect 1K pulldowns to these pins it runs fine. I am not aware of any difference in hardware between these pins and others on the emulated device. If you have had experience with this problem please email me. Regards David Huisman
