Meade used to make a Hand Controller that the #1209 microfocuser's curly lead plugged into.
If you can't find a pre-owned one, you'll have to DIY:
9V DC PP9 battery
100 Ohm variable resistor for speed control
Wire to a DPDT switch to change direction
1/8" Stereo Jack Socket for the curly lead to plug into - Tip and Sleeve wired, Ring not connected.

Check with Shoestring Astronomy, I think they still make a controller for the external unit.

I forgot the DPDT switch needs to be Momentary, so that focus change is not continuous when you throw the switch, only changes while you move the switch.

The 1/8" Stereo Plug in my diagram should of course be a Socket, the Plug is on the curly lead.
