Bill, Did you have any luck finding the driver? I have recently acquired a Feather Touch System with a DH-1 controller, and can't find an ASCOM driver. As a fallback, I have made an Arduino controller which drives the Feather Touch stepper motor, and emulates a Moonlight DRO controller's ASCOM interface. This was developed by Orly - https://www.andico.org/2014/04/arduino-based-motor-focuser-controller.html

Correction - the alt and az motors are dc like the focus motors, not steppers. (Its been a while since I did that bit). Ed

I am salvaging a 10" RXC400 at the moment, so here is my two bobs worth. I picked up a dusty, dirty and electronically expired version very cheaply. At the time my rationale was that, if I couldn't replace the electronics, I could always defork the OTA and have a high quality OTA for my equatorial mount at a bargain price (120 pounds equivalent). So, it depends on the price of the telescope, what is or might go wrong with it, and your mechanical and electronic aptitude. In terms of what might go wrong that you can fix, I believe the Alt and Az motor drive cards are the same as other Meade models and can be swapped out. I think everything else is RCX-specific and hard to find or repair. As noted elsewhere, (https://stargazerslounge.com/topic/285714-light-ringscircles-in-image-after-automatic-background-extraction-in-inpixsight/?tab=comments#comment-3129598 ) you can tolerate the loss of the focus and collimation functions, by adding a focusser to the back of the mirror cell, and by manually collimating with tools from the front. You could probably drill access holes through the front plastic cover to access the collimation/focus leadscrews, and slip plastic tubing over the locked nuts, for a low-risk manual collimation approach. In my case I removed the control and drive electronics, and have replaced them with an Arduino Mega board, interface boards for the encoders and limit switches, and L298N modules to drive the dc focus motors and alt and az stepper motors. Its still a work in progress, but so far, so good. Hope this helps, Ed
