From a website with contact info of Robin Adams, the bIlda1 and bIlda2 DACs were ahead of their time! The bIlda2 is compact and looks very similar to the FB3 DAC – but hails from before 2008!
This was an open source design, with most of the files needed to produce the board being freely available for download. IIRC there is a SMD MCU on the bottom of the PCB.
kLaserplay is the listed application from the archived website of the project. I don't know of any major software support for the board at this time.
