Embryon top pop bumper fires about 4-5 times after boot up.
Then, on a game start, it keeps firing, not really machine gunning, but maybe 2
times a second.
I’ve checked switch adjustment, swapped the SDB, it still does it.
Any thoughts? MPU U11 is my next place to go, I think.
On another note, a tool to release the ckt board nylon mounts can easily
be made from the top of a tube of caulk. Just trim it down till it will slide over the mount.
