Hello!

(06-24-2021 11:21 AM)Sylvain Cote Wrote:  You would need the following: HP-75, IO-ROM, HP-IL/GPIO interface, step motors, equatorial platform, telescope, camera mount, camera & remote camera controller.

And not to forget a step motor driver that can handle input from HP-IB (GPIO). The microcontroller required to build that can easily handle all tasks related to telescope operation therby redering the HP75 useless. And with an unlit display it is useless for this task anyway, not to mention that it's 16kBytes of memory will hold a very very limited catalog of celestial objects only. I think I will continue to control my telescopes using my iPhone...
