I wouldn't expect it to be in that form, necessarily.

You have to obey the file format, but you can specify whatever your 
programmer needs. As I understand it, each line defines both the pin 
number and the polarity of a given signal. So the Tait definition reads 
as:

>vpp=-5

The Vpp enable control is on pin 5 of the parport (d4) and is active low

>vdd=-4

The Vdd enable control is on pin 4 of the parport (d3) and is active low

>clock=3

The programming clock line is on pin 3 (d2) and is active high

>datao=2

The programming data output is on pin 2 (d1) and is active high

>datai=10

The programming data read-back is on pin 10 (ack?) and is active high

>rw=25

I assume this means there's a read/write selector on the Tait 
programmer, on pin 25. Not all programmers have this signal.

If you have a pin-out for the TVLP you should be able to work out the 
correct values to put in the file.
