It appears the search for RTG cards continue as the available supply on the market continues to shrink. A few years ago, I could find a PicassoII card on Ebay occasionally for $200USD or less. These days, if they ever show up, they are going for $300USD or more.

I posted recently about a DIY RTG card for Zorro slot boxes currently under development –> here <– But there is also another one now available for purchase on this link, but it is pricey: –> purchase page <–
