I've been looking for one of these boards for years and haven't seen any around.
Got the WildCard 1 and 2, but the Wildcard Plus is a relative unobtanium item.
If anyone on this forum has one of these, let's talk.
Most of you don't know me, but I'm the one who reverse engineered the EDD_Plus_Card.
There are other Apple ][ cards I've done but haven't published yet.
