paige,
what's the working condition of the monitor? and is this the original one, or a replacement. if replacement does it fit the factory brackets.
i'm not sure i'd give $50 for the cab being it's not exactly what i'm after, but i'd be willing to trade for it. here's some parts i have:
amd k6-2 mobo, cpu, 32 mb ram should run classics on mame, pinmame etc. with no probs.
exidy gun base, swivel, stock, and trigger/grip section(no electronics) from a 440 shooter(cheyenne or combat from the looks of it)- i got these to hack a lightgun into a 440 shooteresque control, i've since decided to just buy a real game and swap out pcb's to play the different games. i actually have 2 complete guns ie. stock,swivel, trigger(1 nos stock!), 2 extra swivels, and 2 extra trigger/grips. i'm going to keep one complete set(with nos stock) just in case, but the rest i'll trade.
neo geo control panel (was originally a karate champ), populated with 2 8 ways and a bunch of micro switch buttons(including a player 1 start with the little guy on it, ply 2 is plain white).
centronics db35 extension cables. i bought a bunch of these for quick disconnects to an encoder. note there's not 35 wires inside, something like 26-27, still pretty useful.
pc flight stick, still in the box. i was going to hack a flight stick on to a happs joy.
(use this and get your tron panel correct, heh heh)
pc trackball
that just about covers all my current tradeables. i might turn up some more stuff a little later when i get into the shop. i'll post if i do.
get back to me if there's anything your interested in.
