Ooo.. how could I forget Fairchild? Thanks!

We're kind of in the "perfect world" phase right now. Reality will 
settle in soon about what we have and do not have and what people are 
willing to loan/donate. But reality is no fun!

The AMD bit slice is new to me. Am I understanding correctly that it is 
not a discrete CPU but rather parts of a CPU that could be used 
together? Probably not a candidate for this exhibit, but I'm already 
having ideas for the next one!

I'd love to find a Zilog Z8000, but don't imagine period correct Z8000s 
are so easy to come by. We have a Z8000 machine in the warehouse, but 
one of the big rules for this product is that no vintage computers will 
be harmed to make it happen.

RCA 1802 should be on the short list, too.

AVR is good suggestion, especially since it is a Harvard Architecture.. 
nice to see that represented.

Thanks for all the ides!
