Dear Amok good morning :) Right questions. Happy to reply. I have two fully functional prototypes (rev 2b) and a spare board for testing. Emulator was developed side by side PC - original Commodore 65. Tested on real hardware with several asm programs useful to test real customs attitude. If you want, you may search in internet about mine near 25 years activity as collector and C65 owner :) Hugs Carlo Pastore
