Wow, this went nowhere. Okay then. I have a TKG2 four-board Donkey Kong boardset, available. It's a TRS (Radarscope) conversion. I received this board in a trade several years ago and had intended on using it for a DK build, but never used it. Time to let it go.
It has not been booted in several years, although it was 100% working when I received it. I'm nervous about plugging it in to test it, as it's been sitting on the shelf for at least 5 years.
I'll trade it straight-up for a DKG4 two-board set in 100% working condition, as a straight trade. Limited time offer.
Eventually I'll work up the nerve to pull my DK away from the wall and fire this board set up. If it still works, I'm headed straight to eBay with it and will likely have it set at a BIN price of $500.
