Quoted from DavidPinballWizz:
And love the tribute to Leon. I've met him in person a few times and was a really nice guy.
+1 Nice to see tribute on the pcb! Did the same thing with the "Sys80 Universal Tester" board that I offered to the community. I'm sure he'd have been thrilled that his projects continue to inspire new ideas & boards!
I also like "THE ULTIMATE"
