Thanks for posting this... I've got a Strange Science and the first thing I did after watching this video is go look it the sound board still had C30 (at around 7:30 in the video) and yes C30 was still there!
So that was my Sunday afternoon, take out the sound board, unsolder C30 and reinstall. I suppose you could just snip it out but I wanted it to look neat. Anyway the board back in now and everything still works.
Potentially you've saved me quite a bit of money if C30 had failed and took out the speech chip. So thanks again.
Also great work with the videos, the banter might be an acquired taste but the information shared is invaluable and your enthusiasm for all things pinball shines through in every video.
Edit: See what happened to U7 in the before and after pics. The little label fell off as I was unsoldering C30 exposing the EPROM erase window. Not sure if the 100W light bulb in the back box could have erased the memory over an extended period of time but put a small piece of electrical tape over anyway then re-glued on the label. Also noted that one of the labels was about to fall off on a MPU EPROM so did the same there just in case.
