+Intersecti
+
+No names on the pcb and the only ascii text is in the sound rom "Intersecti". Has a daughterboard with "Serai-Padova-1" on it
+
+Having disassembled the 1911 code roms, I'd guess that there is a rom in the epoxy block.
+
+I've not had a chance to wire up the board yet, but it might be possible to write a trojan to display the rom(s) at $8000
