Joe – Good news and bad. Good – my board is now working fine; bad – I don't know why! In playing with the CLIP jumper on the FFV2 and disconnecting the RGB monitor with the power on, I accidentally grounded or shorted one or more pins on the RGB output port (my guess is I shorted 12 to 23 ie. 5 volts went to the vertical sync line!). Anyway, both the RGB and VGA screens went blank, and I turned the power off for a period of 'meditation'. When I turned it back on I got a 'software error' message instantly (apparently from Kickstart!), and by the time I realized I was reading the message on the _VGA_ monitor I had already clicked the mouse (so I don't have a record of what the error was), the bootup proceeded otherwise normally, and I suddenly had a rock-steady picture on _both_ monitors. Both pots now work beautifully in fine-tuning the quality of the VGA image. The FFV2 has now been working fine for over 48 hours. I do have the CLIP jumper in the ECS position, even though I have a normal Denise, but it also works in the normal position. If I can make any recommendation from my experience it is _not_ to hit the vertical sync line with 5 volts, but possibly to change the position of the CLIP jumper, turn the machine OFF and then back ON, and see what happens. I never did get to try the scope. Good luck, and keep me informed. I will be talking to the ICD tech about my experience, and will pass along anything of interest. Dick
