This release brings a new 7_7 version of the BeebSCSI PCB that features many physical enhancements (read more about this in the BeebSCSI Hardware Guide available from: https://www.domesday86.com/?page_id=409 ). Importantly, the board design has been moved from the closed-source EagleCAD to the open-source KiCAD providing the ability to use and modify the design without 3rd party license fees. The 7_7 board also adds the (future) possibility for USB support.

The BeebSCSI AVR firmware has been updated with enhancements to the debug (it now reports the emulation mode, the firmware revision and the USB capability of the PCB). The debug has also been modified to output a small amount of information regardless of the debug output settings - this is to assist board builders when performing initial testing (as the previous release version was silent even if the AVR was functioning ok.

The status/activity LED functionality has also been improved. The firmware now supports LED brightness control (with 20 increments of brightness). The LED now glows dimly when the BeebSCSI board is powered and ready. Activity causes the LED to show full brightness and then fade-off providing a much better looking feedback to the user.

Attached in the release files are the firmware builds for the various elements of BeebSCSI. Also included are the Gerber files for the PCB (including all that is required to have PCBs made).
