All 40 units assembled, tested and either posted or are in a jiffy bag and labelled to go.
Well done Jason, a herculean effort
Just a note to all the new owners of BeebSCSI boards - The BeebSCSI project is completely open-source and open-hardware - You are free to view and modify the source-code as much as you like (in fact, I positively encourage anyone with the know-how to do so). The same goes for the BeebSCSI ROM which is optional, but lets you use the 'jukebox' feature to provide as many hard drive images as you can fit on an SD card.
However, if you are not a microcontroller/CPLD boffin then you are most welcome to request feature enhancements (and bugs/issues should you find any) over on the project Github:https://github.com/simoninns/BeebSCSI
Simply open a new issue and label it as enhancement/bug/question as appropriate. I can't promise any time-lines, but I will do my best to work through any requests.
If you'd like a copy of the BeebSCSI ROM (or the boot loader image to re-flash the device) - simply go to the GitHub and click on the 'releases' link. This will take you to a convenient zip file of just the bits you need.
BeebSCSI also has over 70 pages of user guides, hardware guides and technical documentation available including a 'quick start LUN image' that you can simply unzip onto an SD card to get going without having to format the first LUN from floppy using SuperForm (as you would have to with a real Winchester drive):http://www.domesday86.com/?page_id=689
The quick-start guide (and zip file) are here:http://www.domesday86.com/?page_id=400#Quick-start
Edit: If you find anything missing from the documentation or had problems following the guides, please report this on github too - if it confused you, it will probably do the same to others
