RE: HP-75C: use in 2021?
For me, the most important feature of the HP-75, like the HP-41 & HP-71, was HP-IL and its capacity of controlling remote equipment with it.
I could surely see an HP-75 controlling an equatorial platform allowing to capture great pictures with a telescope.
The machine is fast, can go to sleep and be wakeup with a timer, has a great BASIC implementation, good I/O, so perfect for this kind of problem.
You would need the following: HP-75, IO-ROM, HP-IL/GPIO interface, step motors, equatorial platform, telescope, camera mount, camera & remote camera controller.
