Thanks, but that's the one that's been out for a few days, and doesn't have much if any useful information in it (no electrical, no power pinouts, etc, etc). Giorgio & Zephir have both said that the spec will be put on github, and G said it would be updated today... that's what I was looking for.
Yes, it will be put on github with any other support material as soon as it is available in a post pre-alpha state.
Also true: the preliminary spec is exactly that and meant mostly to present the chip front-end and resulting host interface for a broader review. Bitmine is currently working on the first revision of the draft that will be updated ASAP. Since the chip is designed externally (Innosilicon), it takes its time to communicate and settle the final numbers.
Generally, since the Coincraft A1 will be at DIY folks' desks not before late December, there is no need to be impatient. If the provided documentation does not suffice the developer's demands to work on board designs, a full refund will be granted.
Furthermore, given the prolonged availability window (valid till chips are in my hands), there is no need to rush into ordering. Take your time to study the documentation and specs when they are released in their final state, and order only after you decide to work on an own design. Also in this context, please understand that this offer is really meant for DIY folks only, i.e. not for those who want to buy chips and then send them to some 3rd party for assembly. In that case, you should talk to the developer of your choice directly, since with enough interests they can order from Bitmine and get better volume prices. Obviously I do not want to distract people from buying chips, but I want to prevent the chaos the Avalon chip distribution ended for some buyers (ordering chips here and boards there, ending up nowhere).
Cheers
