Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

After 25 years of building and selling controllers, I'm now happily retired. Part of my now unneeded inventory is several million unassigned MAC numbers. I'm offering 64K blocks of sequential MAC numbers to anyone in the group that wants them.

Disclaimer: The MAC numbers are in the IEEE registry as assigned to JK microsystems. To the best of my knowledge, this cannot be changed. 00:90:C2:XX:XX:XX

I would also be happy to be allocated a 64K block.
