| I am trying to use F.4 & F.5 for some general I/0 without any luck. Is there something to do with the JTAC functions that could be causing this? |

| Possibly. Do you have the same result on both of your ZX-1281 Dev Boards? |

Just tried the second board and it appears to work fine.
Any thoughts? |

It is possible that the earlier one was erroneously programmed with JTAG enabled. That would explain why those port bits don't work. If none of the four middle bits (bits 2 to 5) work that is almost certainly what the problem is.
In any event, we will replace the dev board. |

I am really not able to give up the board I have to send it back right now so I will have to work around it for now.
Thanks! |

That's OK. We'll send a new one and you can return the other one later. |
