Thanks. A local operator has a nice currently non-working Big Buck Hunter Safari cab. He told me the computer and guns aren't working but he has had it for over a year and won't bother fixing it. I've thought about making him an offer for the cab and trying to get it working myself but not sure of the cost to do that and don't think I have the skillset either.
So how much is an asrock computer replacement? He told me a new computer is $500 and guns, $300 which seems high. Guessing the monitor also needs a rebuild so probably a bigger project then I can take on.
