We are no longer in the business of selling Bifferboards, however, we have released the bootloader binaries with a license which permits redistribution. They can be found here.
If you wish to buy Bifferboards, console cables and PSUs in small quantities please see this site.
If you want to purchase in larger quantities (MOQ 500 units), please contact MRT Communications. I have explained the situation to them and they are now in a position to ship the WANSER-R with our bootloader.
That's all folks! :-)
