Upgrading Vintage Tower Speakers Part 1: Refinishing

Image
    I go thrift shopping for electronics quite often. Where I am, finding any good electronics will be a challenge. But when you hit it big, it's  REALLY big. An example are these Realistic Optimus T-200's which were only 15 dollars! I had no idea if they worked at all outside of the condition of the speakers, but at that price I'd still be getting some really cool cabinets for cheap. I'll delve into the electronics in a future post, as we are going to sort out their condition first.    They do have a bit of wear and tear from wherever they were before. The veneer is worn the most on top, where possibly a plant pot sat and etched a ring into the surface. The sides are also a bit faded but still not bad.

Cracking it open though reveals a blatantly obvious Serial port labeled J4 (and a board number ending in 69  ⁿᶦᶜᵉ). Luckily ground was marked so finding VCC was easy. I hooked the remaining two pins up to my logic analyzer to see if 1. the port wasn't disabled after flashing the release firmware (such as Nintendo's re-released Game
