networking – Can I buy a single MAC address for a computer project?

So, I’m currently building an 8-Bit computer, and working on getting it connected to the internet, clearly just on a simple LAN to start off, in the hope of making ARP requests and such like which would be pretty cool.
I have had a little look around and I can only find standards companies selling MAC address by the million, this wont work for me.

Does anyone know how someone can accquire a single MAC address for personal use, not making money from it, but registered non the less.

Cheers all!
