I have an ICD Flicker-Free Video 2 board for the 500 and 2000 computers. This board works great and came out of my 2500, I am selling this since I will be parting out the 2500. I don't have a driver disk for this but it is avail.
HERE with more info. the board doesn't include the Denise chip that would come from your current machine. The supplied backplate has a 9 pin plug on it so if you want to use a 15 pin monitor on this you would need a 9 to 15 pin adapter.
I am not sure how hard these are to come by but I'm guessing they aren't too common.
Price $75.00 will include shipping in lower 48. Offer open worldwide and will charge extra $10.00 for shipping. I prefer Paypal but am open to other forms of payment.
Please PM me if interested.
Thank you
