I only had one DEC button (the top one) in-op. It went intermittent first before it failed. I did swap in another known good G1 HC and the same DEC button did not work. When I swapped in a non-Gemini HC w/RJ45 cable all buttons both DEC and RA worked appropriately. I have a G1 HC Serial cable coming. I'm confident that will fix the problem. If not, I'll do the upgrade to G2.?
