Gpusb-ah
A fellow enthusiast sold me his gpusb to allow my laptop to talk to my celestron c8 deluxe. I downloaded the drivers and had unexpected results as the mount did not seem to respond properly. I discovered that this was a special version..Gpusb-ah meant for a very specific mount. Is there a way to get this to work or am I out of luck?

There is one part that would need to be changed to make the conversion. If you have the ability to unsolder the old part and resolder a new one, I can provide the part. If not, you can return it to me and I can make the conversion.

Yes, it is the optoisolator.
The GPUSB-AH should have a TLP620-4 mounted on the bottom of the board.
The GPUSB should have a TLP627-4 mounted on the top of the board (same side as microcontroller). Pin 1 is the square solder pad.
