[TenTec] Orion I RIT/XIT problem

[Vincent Bond]

I have serial number 03C10885 with v2.062a and have been experiencing the same RIT/XIT problem ever since 2.062a was loaded. I have reset, reloaded etc., but the RIT function is intermittent, with the result being that, for the most part, it just does not work. 
Last week, on a lark I reset the PBT/BW step rate to 50 Hz from 10 Hz and the RIT/XIT immediately worked fine for a day or two before it quit. During that time, If I returned to 10 Hz, it stopped functioning. Reset to 50 Hz, it worked. That led me to suspect a firmware issue because the encoder worked perfectly. I still think there may be a firmware issue causing this problem in many cases. 
Being so busy at work, I have not had the time to play with reloading older firware versions to see if the problem when away. Perhaps someone with more free time might investigate that. I hope someone finds the culprit because it is exceedingly annoying to use a ncessary control that works only a small percentage of the time.

I have a theory on the Orion XIT/RIT problem.  I now think the problem is
with the ribbon cable that is connected to J2B in drawing 81917_3.PDF in the
designator A8.   My serial number is
06C10363.  I wonder what other serial numbers are having the same problem.
I bought my Orion 9-16-03.
