Unless that cab is retardedly expensive and rare, a you would have trouble getting a fraction of a TZ for it anyway. A strong TZ is pushing three grand now.
Honestly, that cab is probably worth a couple hundred at most in the real market. Very few people actually collect and have interest in the funky old B&W games (there are obvious exceptions, but usually either popular titles or Computer Space, which is arguably popular anyway). For a nice TZ, you'd probably need about 15 Zaps

All that said, if you were local, I do have a SS Williams that needs a smidge of work, but I'd trade it as-is for your game. Let me know if you move to the New England area!
