Yes the watch shows 0 and -1 and 1, adjusting rpm values changes accordingly

That is good to hear, That means that part of the connection is working.
When you set say 1000rmp what is the result?
also look at the values for the pin stepgen.2.up and stepgen.2.down.
They are the step pulse signal that is to be sent to the parallel port pins.
(You might only be able to notice them blinking at low frequencies.)
It is probable that you need to change the step pulse length for your chip to to be able to detect them.
Change the 1 in this line to what ever it should be or try a reasonably large number, something like 250000
Code:
setp stepgen.2.steplen 1
and add a line for stepspace and set it to the same number as step length.by adding this line.
Code:
setp stepgen.2.stepspace 250000

At the moment I can not see the popup window with Spindle at speed as it is far out to the right and only partially visible.

12" Elotouch screen 800x600 and no better resolution is possible, small size and touch was what I wanted years ago.
Touch is not working properly, next in line to get fixed to work in LCNC. I have no drivers and setup tool for Linux, yet.

Will now go down and try out your prescription, will go online down in the shop.

Cheers
Bengt

Can you try using Hal Scope to watch the parport.0.pin-06-out and parport.0.pin-07-out pins?
Ask if you need instructions how to do that.

Wait, just had an epiphany. Duh, I think we forgot to connect the enable for the spindle's stepgen.
Add this line to your hal file.
Code:
net spindle-enable <= motion.spindle-on => stepgen.2.enable
