Weiler E30 Lathe retrofit?

Any idea why it doesn't have the support software link that is listed for other boards?
Like this one for example: store.mesanet.com/index.php?route=produc...t_id=343&search=7i95
Is it discontinued or something?

I was wondering how come the firmware file is not available for this board.

What I am trying to figure out these days is what features of a 30y old sinumerik 805 I will loose if I switch to linuxcnc. I know the benefits of linuxcnc but I don't know its limitations compared to a professional controller.
The downsides of sinumerik now are:
- an almost dead monitor for which I cannot find a replacement on a decent price
- software in german and quite difficult to transfer programs onto it.
I am talking about tool tip radius compensation, wear offsets, threading and I don't know what other features.
Now that I have played a bit with sinumerik 805 and its custom implementation from Weiler, if I do the retrofit, I will make something closer to what it is now in terms of functionalities.
I am willing to implement my own VCP so I could implement some of the high level functionalities in python (or java, that's what I'm trying to figure out now).

For my weiler lathe, the cam switch for homing the Z axis is somewhere on 1/3 of the total bed length towards the chuck. Before the machine is homed, if the Z axis is past the cam for homing switch, I would need to move the Z axis right before the cam homing switch before starting the procedure.
How can I enable the MPG for jogging the Z axis while not homed, I can move it via keyboard but the MPG-s are working only after the machine is homed.

Thanks, it worked!

This weiler e30 lathe has a 4 way position joystick that sinumerik was using to act as power feed when the spindle was on. 
So while the spindle was on, it was acting like a G1 with the specified feed. 
Is there a way I could achieve the same functionality just by linking hal pins? 
Thanks!
