That was pretty much my assesment below.

Well My trivial programmer really is nothing but a Tait style programmer with
two minor differences:

1) It has no high voltage component.
2) It uses a resistor to separate the data input/output instead of a true
   buffer.

There should be no reason to have to use the software I use. Any Tait style
software that allows for configurable I/O pins should work fine.
