I'm sorry I don't have one for sale, but I'm genuinely interested in why you'd only purchase an original Model B? Is it able to do something that the other models can't for you?
well I am running quite a few avalon 6's and I can use either:
rasp pi model b I have 2
rasp pi 2 model b I have 2
I want an extra 1 or 2 model b's for testing purposes.
I can get one here new

I thought some one may have one or two they do not use.
my testing involves mining speeds and which rasp pi is more stable then the other in a hot room mining the gear.
