Stargate arcade control panel1/16/2024 ![]() I ended up getting a regular 2716 sound ROM (what Stargate uses to begin with) and a doubled-up 2532 to test from Steph at (he was even nice enough to burn the double-up 2532 for free. The code will run out of the lower copy and ignore the upper copy. If you would rather not restrap the sound card, just burn a 2532 with 2 images of the Stargate sound code sequentially it should work just fine. Now this is where "something I read on the Internet" may meet reality. A quick post to KLOV with some pics and I was informed that the sound card was not jumpered correct and that it had Joust sound ROMs in it. I also noticed that the sounds were not the same as my other Stargate. The boards arrived a few days later and I was able to get 1 working board out of the bunch. I ended up winning for $14.99 + $5.99 shipping. Knowing now that I needed an interface board I figured I would take a chance buying 3 untested interface boards from an eBay auction. I pulled the interface board from my upright and tested in the mini and the stuck on reverse went away. I unplugged the interface board and the stuck on reverse went away. ![]() If the reverse switch was not stuck on anymore then the problem was with the interface board if it was stuck on then the problem lays on the CPU board. ![]() Another suggestion was to unplug the interface board and go back into the switch test. I wiggled the ribbon cable again and they went away except for reverse. I did and a couple of other switches came stuck on. I was instructed to first try to wiggle the ribbon cable on the interface board as they are known to cause issues. I posted a thread on KLOV to find out was was the cause of the problem. ![]()
