Hm, so it is in fact done by KS as I was suspecting but it doesn't even need to detect the external clock. It's enough to detect external sync pulses.. clever. I believed clock to be the primary driver. Now I would really like to be 100% sure. Anyone with an Amiga and a working genlock willing to verify this on a real hardware? -- SD! - http://e4aws.silverdr.com/ Message was sent through the cbm-hackers mailing listReceived on 2017-11-07 17:00:03
