I am digging out some of the rare stuff in my collection (after 20+ years of storage) and wondering what the value on some of them are...
Specifically, here's an Atari 1200 prototype unit. I haven't tried to turn it on, but it worked years ago when I last powered it up.
I have a couple of 8-bit prototypes, 5200 prototypes, and quite a few 2600 prototypes I'll be asking about soon, too!
Thanks for your help...
