Was it a successful clear and key? I know your not a newbie, did you check your legs on SB? Is the monitor showing anything. I love the vision platform. I built one today and forgot to remove the 363's. Shows anyone can have a senior moment. Put in the 248's and done.
Clear gave 2 ambers key gave 2 ambers
Game boots to call attendant on vfd and initializing please wait on the upper monitor it goes no further than that ....
Sb is 70
Sgs are 341s abs version is 11gxo
Sheet shows 224 and 31 are correct clear and key , they are freshly burnt, mpu was swapped , nothing changes. All connections to the top box confirmed good, game worked fine till I tried to key it to change denom
