If a new chip is found to be useable on a modified k16 unit, would there be a further refund on parts which were purchased for this group buy, or a credit to those of us that stay the course?
Yeah, kind of insane that there is as steamboat said a "TON" of parts -- that apparently he is keeping, that you paid for.
I don't think this is the case.
I believe if you get the 25% refund, the parts will also be sent to you.those customers which purchased assembly will have the option of receiving the components purchased for production of the original units if they so choose.
(Emphasis mine.)
It says it's an option, not the default. I suspect there would be a shipping charge for receiving the parts, since the most recent update says he's offering 100% refund of the shipping fees.
The way I read it, there will only be an option for getting your components shipped if they DON'T do a next gen board of some kind:
"In the event we are unable to produce a redesigned unit, those customers which purchased assembly will have the option of receiving the components purchased for production of the original units if they so choose."
If they DO produce a next gen unit, you'll be "credited the full value of the components reused in producing the new units". Not sure what happens to the components that aren't reused. Also not sure what "credited" means. Sounds like a credit towards the purchase of a next gen miner...
