I picked up a SST a couple months ago, and I'm really enjoying it! Lots of fun for the novice player and plenty of challenge for the skilled player. Just the kind of game I like to have in my gameroom.
Anyway, while I was fixing up the game, I decided to make a few enhancements as well. Some have been covered here and in other threads (like adding the the second speaker). One thing I hadn't seen done before that I thought would look cool was if the 7-segment LED digits on the playfield were the same color as their corresponding bug/target (instead of all red). Unfortunately, you can't get blue digits that use the same pinout as what the original board uses, so it takes a bit of work.... Here's what the proto looks like:
Please excuse the crappy cell-phone pic... it looks considerably better in person.
So I was considering having some 4-color display boards fabricated that would be a simple drop-in replacement for the original board. Any interest?
