An equatorial platform also known as a Poncet platform will do what you want. These were popular many years ago before GOTO was common. I’m old school too and would rather use a map and memory in the car than a GPS and same for the sky.
Just search “equatorial platforms for telescopes”
There are expensive options with dual axis motors suitable for photography as well as DIY kits.
An EQ platform needs to be made for your latitude and be sturdy enough to take the weight of the telescope. You can simply position the entire Dob ground board on the platform or remove the ground board altogether and the platform itself becomes the ground board.
There was also a product by JMI telescopes (Jimsmobile) called Track’N’Train and was available for Meade Lightbridge Dobs. I have this on my 16” f4.5 but tend not to bother with it. Depending on the position of the target T’N’T either works well or not so well. I also have an EQ platform for my smaller Dobs which I only use for planetary observing when wanting the target to stay fixed for longer periods. An EQ platform will get you about 45min of tracking before needing to be reset, (takes seconds to reset).
There is also ServoCAT which will give you GOTO but you can simply track Alt-Az if you want. You’ll get field rotation over time but for visual it doesn’t matter and the rotation is slow. I’ve never used ServoCAT and am unsure if you can simply push to a new location manually and it picks up from its new position. I would not like it if I had to use the motors to drive it everywhere.
