It is great that this module is finally available. Here's what I wrote about it on my blog:

was the module that brought Blackmoor back to TSR and D&D. Supplement II: Blackmoor and the Judges Guild booklet the First Fantasy Campaign were the Blackmoor releases available to gamers in the 1970s, but in the following decade, gamers would be treated with four high production value modules that Dave Arneson co wrote with SPI designer David J. Ritchie.

DA1 was the first in the new series and gives a great overview of the setting that can be used as a toolkit to run sandbox style adventures in Dave Arneson's original setting. In addition it features an adventure revolving around King Uther being kidnapped. This adventure also has information for bringing AC1000 Known World /Mystara characters back to the era of Blackmoor.

After a long wait, this module is now available as a PDF release at Drivethru. DA2 Temple of the Frog and Supplement II: Blackmoor have been available for a while now, but it is great seeing DA1 finally available for fans of Blackmoor. Let us hope we don't have to wait this long to get the last two modules in the DA series. This is a must-have for any true Blackmoor fan.

This is one of the few items I tracked down on eBay many years ago, when my volunteer position suddenly turned into a paying job. Best $30ish I ever spent.

I'd say that true and hardcore Blackmoor fans got this plenty of time ago, but having it available this way will make it accessible to potential future fans that perhaps weren't yet born when it was written in the first instance.
It is anyway an historical document.
