Help me piece together my Tech 1a please ... pics of what I currently have inside ---

[alwayscode390]

Here is the top of the handheld.

I think its 26 female pins.

Then there is a phone plug with a single female plug below it (power?) on the left side , and a phone plug on the right side.

It takes a master cartridge or an auxillary cartridge.

Here is a pic of the top, above the screen:



This unit originally came with a MARINE cord and cartridge ... I wonder if it was custom swapped out with a different piece up top to connect the cord to?

Thanks for pointing out I have a Tech 1 power/data cord ... I didn't even realize it was different than a tech 1a , that helps me a lot ! ---
