Re: IEEE Adapter

That's the only thing it is doing (converting PET edge connector to female
IEEE-488.)  My apologies for not describing it in more detail (the curse of
being too close to a project).

Though, is that all it should do?  I mean, I'm not asking for suggestions
to add lots to the device, but:

    * Is there a project out that adds joysticks or IEC routines to the
      IEEE pins?  If so, should I put a footprint for a joystick or an IEC
      port on the PCB?
    * I probably could fit an RTC footprint on some pins there in a way
      that would not interfere with normal operation...
          o EEPROM would also work, if the above works.
    * blinkelights on the signal lines, to allow it to be used for
      debugging IEEE issues?  (Obviously, this would need a power source,
      but that's not insurmountable)

IEEE-488 is not my forte, but I do hate to waste space on a PCB.
