[UtVgG] Sell or Trade me your working Tempest board

If you have a *working* Tempest board, I'd like to buy/trade for it. I have working Asteroids, Pac-Man, Ms.Pac, Donkey Kong, DK Jr, Centipede, Marquees, a working WG 4900 monitor, etc. If you are the handy type (this is you Chris Strong) I have 2 Tempest boards + $ that I would swap for 1 good one. One of my boards plays blind, one is DOA. Both are complete and have good ROMs. And a public thanks to Kurt, who loaned me several boards in an attempt to get one working. I did get one to play blind after about 3 hours of fiddling, but there is no X or Y output. And no, it's not the one I'm offering to trade. :) Sean McLachlan
