Re: Why AP mount don't have a USB port?

I hope it's clear that Adam said that "the tables have turned", not I!

I greatly prefer servo motors over hot, inefficient steppers and also think
that the choice of RS-232 is a sound one, for now and the foreseeable
future... until either a modular interface or Ethernet port becomes
available!

As a microcontroller programmer myself, I believe that AP has made all of
the right choices for all of the right decisions when it comes to premium
mounts.

As for people having perpetual problems with serial ports, I believe that
about 98% of those problems can be traced back to junky serial-USB adapters,
junky device drivers and people accidentally installing 32-bit device
drivers on 64-bit operating systems.

The tables have turned? I don't get that. In what way have the tables
turned?
We make a precision mechanical product, driven by a dedicated servodrive.
That servodrive can be updated rather easily compared to the mechanics. We
do not intend to change the mechanics or the precision of the mount. Right
now the mount is capable of tracking stars over the sky to sub-arc sec
levels for quite some time without any need for guiding. Where exactly have
we missed the boat?

Yup. 10Micron mounts use such Linux based control system. A big advantage of

Linux over other RTOS's is a large developer community and a big knowledge
base.
I have a feeling that the tables have turned and A-P is playing a catch-up.
