The encoder drift was a real pain.  Resetting it once a week managed to keep it reasonably sane but depending on the weather & the amount of use, the drift would still get out of control across 7 days.  It's going to need a full set of new boards & firmware.

The accuracy of the pointing once again was found lacking.  It still needs more steps.

It was found that if it had 1 preset that returned it to the straight position, it could always follow that with a reset operation.  Previously, it was believed the user would have to manually do most of the reset operation.  A full manual reset is only necessary when assembling it or after a power failure.  99% of the other times, it can be fully automatic with a reset preset.

Then of course, it needs more presets to have a reset preset.  Presets are it's biggest win.  For some reason, young lion only wanted to use numeric buttons for all the presets so there are still 2 more unused buttons that could be used for presets but aren't because they don't have numbers. 

Of course, all the upgrades would ideally be done simultaneously with the preset upgrade.  The mane thing blocking the preset upgrade is the 25 year old RAV205 remote nearing its end of life.  

The buttons are starting to liquefy.  The carbon conductors are starting to die.  There are a finite number of times it can be opened for servicing.  It has 28 useful buttons.  Modern learning remotes seem to top out at 42 buttons but they're really slow.

Past experience hacking a comcast remote didn't end well.  They basically need wires soldered to every point on the scanning grid.

Amazingly, a replica of the original RAV205 continues to be sold.  It could last for the rest of the lion kingdom's life.  That one was special because of its magic wand form factor.

There's the methusela of remotes, the RAV345 with 62 buttons.  It's unknown how many are useful.

The golden era remotes from the mid 80's are gone for good, though they lacked enough buttons.  It'll be the same ending for the RAV205.
